meson: Move all code generation scripts to utils/codegen/

We have multiple code generation scripts in utils/, mixed with other
miscellaneous utilities, as well as a larger code base based on mojom in
utils/ipc/. To make code sharing easier between the generator scripts,
without creating a mess in the utils/ directory, move all the code
generation code to utils/codegen/.

-# Mojom Interface Definition Language (IDL)
-This document is a subset of the [Mojo documentation](/mojo/README.md).
-
-[TOC]
-
-## Overview
-
-Mojom is the IDL for Mojo interfaces. Given a `.mojom` file, the
-[bindings
-generator](https://cs.chromium.org/chromium/src/mojo/public/tools/bindings/) can
-output bindings for any supported language: **C++**, **JavaScript**, or
-**Java**.
-
-For a trivial example consider the following hypothetical Mojom file we write to
-`//services/widget/public/mojom/frobinator.mojom`:
-
-```
-module widget.mojom;
-
-interface Frobinator {
-  Frobinate();
-};
-```
-
-This defines a single [interface](#Interfaces) named `Frobinator` in a
-[module](#Modules) named `widget.mojom` (and thus fully qualified in Mojom as
-`widget.mojom.Frobinator`.) Note that many interfaces and/or other types of
-definitions (structs, enums, *etc.*) may be included in a single Mojom file.
-
-If we add a corresponding GN target to
-`//services/widget/public/mojom/BUILD.gn`:
-
-```
-import("mojo/public/tools/bindings/mojom.gni")
-
-mojom("mojom") {
-  sources = [
-    "frobinator.mojom",
-  ]
-}
-```
-
-and then build this target:
-
-```
-ninja -C out/r services/widget/public/mojom
-```
-
-we'll find several generated sources in our output directory:
-
-```
-out/r/gen/services/widget/public/mojom/frobinator.mojom.cc
-out/r/gen/services/widget/public/mojom/frobinator.mojom.h
-out/r/gen/services/widget/public/mojom/frobinator.mojom-shared.h
-etc...
-```
-
-Each of these generated source modules includes a set of definitions
-representing the Mojom contents in C++. You can also build or depend on suffixed
-target names to get bindings for other languages. For example,
-
-```
-ninja -C out/r services/widget/public/mojom:mojom_js
-ninja -C out/r services/widget/public/mojom:mojom_java
-```
-
-would generate JavaScript and Java bindings respectively, in the same generated
-output directory.
-
-For more details regarding the generated
-outputs please see
-[documentation for individual target languages](#Generated-Code-For-Target-Languages).
-
-## Mojom Syntax
-
-Mojom IDL allows developers to define **structs**, **unions**, **interfaces**,
-**constants**, and **enums**, all within the context of a **module**. These
-definitions are used to generate code in the supported target languages at build
-time.
-
-Mojom files may **import** other Mojom files in order to reference their
-definitions.
-
-### Primitive Types
-Mojom supports a few basic data types which may be composed into structs or used
-for message parameters.
-
-| Type                          | Description
-|-------------------------------|-------------------------------------------------------|
-| `bool`                        | Boolean type (`true` or `false`.)
-| `int8`, `uint8`               | Signed or unsigned 8-bit integer.
-| `int16`, `uint16`             | Signed or unsigned 16-bit integer.
-| `int32`, `uint32`             | Signed or unsigned 32-bit integer.
-| `int64`, `uint64`             | Signed or unsigned 64-bit integer.
-| `float`, `double`             | 32- or 64-bit floating point number.
-| `string`                      | UTF-8 encoded string.
-| `array<T>`                    | Array of any Mojom type *T*; for example, `array<uint8>` or `array<array<string>>`.
-| `array<T, N>`                 | Fixed-length array of any Mojom type *T*. The parameter *N* must be an integral constant.
-| `map<S, T>`                   | Associated array mapping values of type *S* to values of type *T*. *S* may be a `string`, `enum`, or numeric type.
-| `handle`                      | Generic Mojo handle. May be any type of handle, including a wrapped native platform handle.
-| `handle<message_pipe>`        | Generic message pipe handle.
-| `handle<shared_buffer>`       | Shared buffer handle.
-| `handle<data_pipe_producer>`  | Data pipe producer handle.
-| `handle<data_pipe_consumer>`  | Data pipe consumer handle.
-| `handle<platform>`            | A native platform/OS handle.
-| *`pending_remote<InterfaceType>`*             | Any user-defined Mojom interface type. This is sugar for a strongly-typed message pipe handle which should eventually be used to make outgoing calls on the interface.
-| *`pending_receiver<InterfaceType>`*            | A pending receiver for any user-defined Mojom interface type. This is sugar for a more strongly-typed message pipe handle which is expected to receive request messages and should therefore eventually be bound to an implementation of the interface.
-| *`pending_associated_remote<InterfaceType>`*  | An associated interface handle. See [Associated Interfaces](#Associated-Interfaces)
-| *`pending_associated_receiver<InterfaceType>`* | A pending associated receiver. See [Associated Interfaces](#Associated-Interfaces)
-| *T*?                          | An optional (nullable) value. Primitive numeric types (integers, floats, booleans, and enums) are not nullable. All other types are nullable.
-
-### Modules
-
-Every Mojom file may optionally specify a single **module** to which it belongs.
-
-This is used strictly for aggregating all defined symbols therein within a
-common Mojom namespace. The specific impact this has on generated bindings code
-varies for each target language. For example, if the following Mojom is used to
-generate bindings:
-
-```
-module business.stuff;
-
-interface MoneyGenerator {
-  GenerateMoney();
-};
-```
-
-Generated C++ bindings will define a class interface `MoneyGenerator` in the
-`business::stuff` namespace, while Java bindings will define an interface
-`MoneyGenerator` in the `org.chromium.business.stuff` package. JavaScript
-bindings at this time are unaffected by module declarations.
-
-**NOTE:** By convention in the Chromium codebase, **all** Mojom files should
-declare a module name with at least (and preferably exactly) one top-level name
-as well as an inner `mojom` module suffix. *e.g.*, `chrome.mojom`,
-`business.mojom`, *etc.*
-
-This convention makes it easy to tell which symbols are generated by Mojom when
-reading non-Mojom code, and it also avoids namespace collisions in the fairly
-common scenario where you have a real C++ or Java `Foo` along with a
-corresponding Mojom `Foo` for its serialized representation.
-
-### Imports
-
-If your Mojom references definitions from other Mojom files, you must **import**
-those files. Import syntax is as follows:
-
-```
-import "services/widget/public/mojom/frobinator.mojom";
-```
-
-Import paths are always relative to the top-level directory.
-
-Note that circular imports are **not** supported.
-
-### Structs
-
-Structs are defined using the **struct** keyword, and they provide a way to
-group related fields together:
-
-``` cpp
-struct StringPair {
-  string first;
-  string second;
-};
-```
-
-Struct fields may be comprised of any of the types listed above in the
-[Primitive Types](#Primitive-Types) section.
-
-Default values may be specified as long as they are constant:
-
-``` cpp
-struct Request {
-  int32 id = -1;
-  string details;
-};
-```
-
-What follows is a fairly
-comprehensive example using the supported field types:
-
-``` cpp
-struct StringPair {
-  string first;
-  string second;
-};
-
-enum AnEnum {
-  kYes,
-  kNo
-};
-
-interface SampleInterface {
-  DoStuff();
-};
-
-struct AllTheThings {
-  // Note that these types can never be marked nullable!
-  bool boolean_value;
-  int8 signed_8bit_value = 42;
-  uint8 unsigned_8bit_value;
-  int16 signed_16bit_value;
-  uint16 unsigned_16bit_value;
-  int32 signed_32bit_value;
-  uint32 unsigned_32bit_value;
-  int64 signed_64bit_value;
-  uint64 unsigned_64bit_value;
-  float float_value_32bit;
-  double float_value_64bit;
-  AnEnum enum_value = AnEnum.kYes;
-
-  // Strings may be nullable.
-  string? maybe_a_string_maybe_not;
-
-  // Structs may contain other structs. These may also be nullable.
-  StringPair some_strings;
-  StringPair? maybe_some_more_strings;
-
-  // In fact structs can also be nested, though in practice you must always make
-  // such fields nullable -- otherwise messages would need to be infinitely long
-  // in order to pass validation!
-  AllTheThings? more_things;
-
-  // Arrays may be templated over any Mojom type, and are always nullable:
-  array<int32> numbers;
-  array<int32>? maybe_more_numbers;
-
-  // Arrays of arrays of arrays... are fine.
-  array<array<array<AnEnum>>> this_works_but_really_plz_stop;
-
-  // The element type may be nullable if it's a type which is allowed to be
-  // nullable.
-  array<AllTheThings?> more_maybe_things;
-
-  // Fixed-size arrays get some extra validation on the receiving end to ensure
-  // that the correct number of elements is always received.
-  array<uint64, 2> uuid;
-
-  // Maps follow many of the same rules as arrays. Key types may be any
-  // non-handle, non-collection type, and value types may be any supported
-  // struct field type. Maps may also be nullable.
-  map<string, int32> one_map;
-  map<AnEnum, string>? maybe_another_map;
-  map<StringPair, AllTheThings?>? maybe_a_pretty_weird_but_valid_map;
-  map<StringPair, map<int32, array<map<string, string>?>?>?> ridiculous;
-
-  // And finally, all handle types are valid as struct fields and may be
-  // nullable. Note that interfaces and interface requests (the "Foo" and
-  // "Foo&" type syntax respectively) are just strongly-typed message pipe
-  // handles.
-  handle generic_handle;
-  handle<data_pipe_consumer> reader;
-  handle<data_pipe_producer>? maybe_writer;
-  handle<shared_buffer> dumping_ground;
-  handle<message_pipe> raw_message_pipe;
-  pending_remote<SampleInterface>? maybe_a_sample_interface_client_pipe;
-  pending_receiver<SampleInterface> non_nullable_sample_pending_receiver;
-  pending_receiver<SampleInterface>? nullable_sample_pending_receiver;
-  pending_associated_remote<SampleInterface> associated_interface_client;
-  pending_associated_receiver<SampleInterface> associated_pending_receiver;
-  pending_associated_receiver<SampleInterface>? maybe_another_pending_receiver;
-};
-```
-
-For details on how all of these different types translate to usable generated
-code, see
-[documentation for individual target languages](#Generated-Code-For-Target-Languages).
-
-### Unions
-
-Mojom supports tagged unions using the **union** keyword. A union is a
-collection of fields which may take the value of any single one of those fields
-at a time. Thus they provide a way to represent a variant value type while
-minimizing storage requirements.
-
-Union fields may be of any type supported by [struct](#Structs) fields. For
-example:
-
-```cpp
-union ExampleUnion {
-  string str;
-  StringPair pair;
-  int64 id;
-  array<uint64, 2> guid;
-  SampleInterface iface;
-};
-```
-
-For details on how unions like this translate to generated bindings code, see
-[documentation for individual target languages](#Generated-Code-For-Target-Languages).
-
-### Enumeration Types
-
-Enumeration types may be defined using the **enum** keyword either directly
-within a module or nested within the namespace of some struct or interface:
-
-```
-module business.mojom;
-
-enum Department {
-  kSales = 0,
-  kDev,
-};
-
-struct Employee {
-  enum Type {
-    kFullTime,
-    kPartTime,
-  };
-
-  Type type;
-  // ...
-};
-```
-
-C++ constant-style enum value names are preferred as specified in the
-[Google C++ Style Guide](https://google.github.io/styleguide/cppguide.html#Enumerator_Names).
-
-Similar to C-style enums, individual values may be explicitly assigned within an
-enum definition. By default, values are based at zero and increment by
-1 sequentially.
-
-The effect of nested definitions on generated bindings varies depending on the
-target language. See [documentation for individual target languages](#Generated-Code-For-Target-Languages).
-
-### Constants
-
-Constants may be defined using the **const** keyword either directly within a
-module or nested within the namespace of some struct or interface:
-
-```
-module business.mojom;
-
-const string kServiceName = "business";
-
-struct Employee {
-  const uint64 kInvalidId = 0;
-
-  enum Type {
-    kFullTime,
-    kPartTime,
-  };
-
-  uint64 id = kInvalidId;
-  Type type;
-};
-```
-
-The effect of nested definitions on generated bindings varies depending on the
-target language. See [documentation for individual target languages](#Generated-Code-For-Target-Languages).
-
-### Features
-
-Features can be declared with a `name` and `default_state` and can be attached
-in mojo to interfaces or methods using the `RuntimeFeature` attribute. If the
-feature is disabled at runtime, the method will crash and the interface will
-refuse to be bound / instantiated. Features cannot be serialized to be sent over
-IPC at this time.
-
-```
-module experimental.mojom;
-
-feature kUseElevators {
-  const string name = "UseElevators";
-  const bool default_state = false;
-}
-
-[RuntimeFeature=kUseElevators]
-interface Elevator {
-  // This interface cannot be bound or called if the feature is disabled.
-}
-
-interface Building {
-  // This method cannot be called if the feature is disabled.
-  [RuntimeFeature=kUseElevators]
-  CallElevator(int floor);
-
-  // This method can be called.
-  RingDoorbell(int volume);
-}
-```
-
-### Interfaces
-
-An **interface** is a logical bundle of parameterized request messages. Each
-request message may optionally define a parameterized response message. Here's
-an example to define an interface `Foo` with various kinds of requests:
-
-```
-interface Foo {
-  // A request which takes no arguments and expects no response.
-  MyMessage();
-
-  // A request which has some arguments and expects no response.
-  MyOtherMessage(string name, array<uint8> bytes);
-
-  // A request which expects a single-argument response.
-  MyMessageWithResponse(string command) => (bool success);
-
-  // A request which expects a response with multiple arguments.
-  MyMessageWithMoarResponse(string a, string b) => (int8 c, int8 d);
-};
-```
-
-Anything which is a valid struct field type (see [Structs](#Structs)) is also a
-valid request or response argument type. The type notation is the same for both.
-
-### Attributes
-
-Mojom definitions may have their meaning altered by **attributes**, specified
-with a syntax similar to Java or C# attributes. There are a handle of
-interesting attributes supported today.
-
-* **`[Sync]`**:
-  The `Sync` attribute may be specified for any interface method which expects a
-  response. This makes it so that callers of the method can wait synchronously
-  for a response. See [Synchronous
-  Calls](/mojo/public/cpp/bindings/README.md#Synchronous-Calls) in the C++
-  bindings documentation. Note that sync methods are only actually synchronous
-  when called from C++.
-
-* **`[NoInterrupt]`**:
-  When a thread is waiting for a reply to a `Sync` message, it's possible to be
-  woken up to dispatch other unrelated incoming `Sync` messages. This measure
-  helps to avoid deadlocks. If a `Sync` message is also marked as `NoInterrupt`
-  however, this behavior is disabled: instead the calling thread will only wake
-  up for the precise message being waited upon. This attribute must be used with
-  extreme caution, because it can lead to deadlocks otherwise.
-
-* **`[Default]`**:
-  The `Default` attribute may be used to specify an enumerator value or union
-  field that will be used if an `Extensible` enumeration or union does not
-  deserialize to a known value on the receiver side, i.e. the sender is using a
-  newer version of the enum or union. This allows unknown values to be mapped to
-  a well-defined value that can be appropriately handled.
-
-  Note: The `Default` field for a union must be of nullable or integral type.
-  When a union is defaulted to this field, the field takes on the default value
-  for its type: null for nullable types, and zero/false for integral types.
-
-* **`[Extensible]`**:
-  The `Extensible` attribute may be specified for any enum or union definition.
-  For enums, this essentially disables builtin range validation when receiving
-  values of the enum type in a message, allowing older bindings to tolerate
-  unrecognized values from newer versions of the enum.
-
-  If an enum value within an extensible enum definition is affixed with the
-  `Default` attribute, out-of-range values for the enum will deserialize to that
-  default value. Only one enum value may be designated as the `Default`.
-
-  Similarly, a union marked `Extensible` will deserialize to its `Default` field
-  when an unrecognized field is received. Extensible unions MUST specify exactly
-  one `Default` field, and the field must be of nullable or integral type. When
-  defaulted to this field, the value is always null/zero/false as appropriate.
-
-  An `Extensible` enumeration REQUIRES that a `Default` value be specified,
-  so all new extensible enums should specify one.
-
-* **`[Native]`**:
-  The `Native` attribute may be specified for an empty struct declaration to
-  provide a nominal bridge between Mojo IPC and legacy `IPC::ParamTraits` or
-  `IPC_STRUCT_TRAITS*` macros. See [Repurposing Legacy IPC
-  Traits](/docs/mojo_ipc_conversion.md#repurposing-and-invocations) for more
-  details. Note support for this attribute is strictly limited to C++ bindings
-  generation.
-
-* **`[MinVersion=N]`**:
-  The `MinVersion` attribute is used to specify the version at which a given
-  field, enum value, interface method, or method parameter was introduced.
-  See [Versioning](#Versioning) for more details. `MinVersion` does not apply
-  to interfaces, structs or enums, but to the fields of those types.
-  `MinVersion` is not a module-global value, but it is ok to pretend it is by
-  skipping versions when adding fields or parameters.
-
-* **`[Stable]`**:
-  The `Stable` attribute specifies that a given mojom type or interface
-  definition can be considered stable over time, meaning it is safe to use for
-  things like persistent storage or communication between independent
-  version-skewed binaries. Stable definitions may only depend on builtin mojom
-  types or other stable definitions, and changes to such definitions MUST
-  preserve backward-compatibility through appropriate use of versioning.
-  Backward-compatibility of changes is enforced in the Chromium tree using a
-  strict presubmit check. See [Versioning](#Versioning) for more details on
-  backward-compatibility constraints.
-
-* **`[Uuid=<UUID>]`**:
-  Specifies a UUID to be associated with a given interface. The UUID is intended
-  to remain stable across all changes to the interface definition, including
-  name changes. The value given for this attribute should be a standard UUID
-  string representation as specified by RFC 4122. New UUIDs can be generated
-  with common tools such as `uuidgen`.
-
-* **`[RuntimeFeature=feature]`**
-  The `RuntimeFeature` attribute should reference a mojo `feature`. If this
-  feature is enabled (e.g. using `--enable-features={feature.name}`) then the
-  interface behaves entirely as expected. If the feature is not enabled the
-  interface cannot be bound to a concrete receiver or remote - attempting to do
-  so will result in the receiver or remote being reset() to an unbound state.
-  Note that this is a different concept to the build-time `EnableIf` directive.
-  `RuntimeFeature` is currently only supported for C++ bindings and has no
-  effect for, say, Java or TypeScript bindings (see https://crbug.com/1278253).
-
-* **`[EnableIf=value]`**:
-  The `EnableIf` attribute is used to conditionally enable definitions when the
-  mojom is parsed. If the `mojom` target in the GN file does not include the
-  matching `value` in the list of `enabled_features`, the definition will be
-  disabled. This is useful for mojom definitions that only make sense on one
-  platform. Note that the `EnableIf` attribute can only be set once per
-  definition and cannot be set at the same time as `EnableIfNot`. Also be aware
-  that only one condition can be tested, `EnableIf=value,xyz` introduces a new
-  `xyz` attribute. `xyz` is not part of the `EnableIf` condition that depends
-  only on the feature `value`. Complex conditions can be introduced via
-  enabled_features in `build.gn` files.
-
-* **`[EnableIfNot=value]`**:
-  The `EnableIfNot` attribute is used to conditionally enable definitions when
-  the mojom is parsed. If the `mojom` target in the GN file includes the
-  matching `value` in the list of `enabled_features`, the definition will be
-  disabled. This is useful for mojom definitions that only make sense on all but
-  one platform. Note that the `EnableIfNot` attribute can only be set once per
-  definition and cannot be set at the same time as `EnableIf`.
-
-* **`[ServiceSandbox=value]`**:
-  The `ServiceSandbox` attribute is used in Chromium to tag which sandbox a
-  service hosting an implementation of interface will be launched in. This only
-  applies to `C++` bindings. `value` should match a constant defined in an
-  imported `sandbox.mojom.Sandbox` enum (for Chromium this is
-  `//sandbox/policy/mojom/sandbox.mojom`), such as `kService`.
-
-* **`[RequireContext=enum]`**:
-  The `RequireContext` attribute is used in Chromium to tag interfaces that
-  should be passed (as remotes or receivers) only to privileged process
-  contexts. The process context must be an enum that is imported into the
-  mojom that defines the tagged interface. `RequireContext` may be used in
-  future to DCHECK or CHECK if remotes are made available in contexts that
-  conflict with the one provided in the interface definition. Process contexts
-  are not the same as the sandbox a process is running in, but will reflect
-  the set of capabilities provided to the service.
-
-* **`[AllowedContext=enum]`**:
-  The `AllowedContext` attribute is used in Chromium to tag methods that pass
-  remotes or receivers of interfaces that are marked with a `RequireContext`
-  attribute. The enum provided on the method must be equal or better (lower
-  numerically) than the one required on the interface being passed. At present
-  failing to specify an adequate `AllowedContext` value will cause mojom
-  generation to fail at compile time. In future DCHECKs or CHECKs might be
-  added to enforce that method is only called from a process context that meets
-  the given `AllowedContext` value. The enum must of the same type as that
-  specified in the interface's `RequireContext` attribute. Adding an
-  `AllowedContext` attribute to a method is a strong indication that you need
-   a detailed security review of your design - please reach out to the security
-   team.
-
-* **`[SupportsUrgent]`**:
-  The `SupportsUrgent` attribute is used in conjunction with
-  `mojo::UrgentMessageScope` in Chromium to tag messages as having high
-  priority. The IPC layer notifies the underlying scheduler upon both receiving
-  and processing an urgent message. At present, this attribute only affects
-  channel associated messages in the renderer process.
-
-## Generated Code For Target Languages
-
-When the bindings generator successfully processes an input Mojom file, it emits
-corresponding code for each supported target language. For more details on how
-Mojom concepts translate to a given target language, please refer to the
-bindings API documentation for that language:
-
-* [C++ Bindings](/mojo/public/cpp/bindings/README.md)
-* [JavaScript Bindings](/mojo/public/js/README.md)
-* [Java Bindings](/mojo/public/java/bindings/README.md)
-
-## Message Validation
-
-Regardless of target language, all interface messages are validated during
-deserialization before they are dispatched to a receiving implementation of the
-interface. This helps to ensure consistent validation across interfaces without
-leaving the burden to developers and security reviewers every time a new message
-is added.
-
-If a message fails validation, it is never dispatched. Instead a **connection
-error** is raised on the binding object (see
-[C++ Connection Errors](/mojo/public/cpp/bindings/README.md#Connection-Errors),
-[Java Connection Errors](/mojo/public/java/bindings/README.md#Connection-Errors),
-or
-[JavaScript Connection Errors](/mojo/public/js/README.md#Connection-Errors) for
-details.)
-
-Some baseline level of validation is done automatically for primitive Mojom
-types.
-
-### Non-Nullable Objects
-
-Mojom fields or parameter values (*e.g.*, structs, interfaces, arrays, *etc.*)
-may be marked nullable in Mojom definitions (see
-[Primitive Types](#Primitive-Types).) If a field or parameter is **not** marked
-nullable but a message is received with a null value in its place, that message
-will fail validation.
-
-### Enums
-
-Enums declared in Mojom are automatically validated against the range of legal
-values. For example if a Mojom declares the enum:
-
-``` cpp
-enum AdvancedBoolean {
-  kTrue = 0,
-  kFalse = 1,
-  kFileNotFound = 2,
-};
-```
-
-and a message is received with the integral value 3 (or anything other than 0,
-1, or 2) in place of some `AdvancedBoolean` field or parameter, the message will
-fail validation.
-
-*** note
-NOTE: It's possible to avoid this type of validation error by explicitly marking
-an enum as [Extensible](#Attributes) if you anticipate your enum being exchanged
-between two different versions of the binding interface. See
-[Versioning](#Versioning).
-***
-
-### Other failures
-
-There are a  host of internal validation errors that may occur when a malformed
-message is received, but developers should not be concerned with these
-specifically; in general they can only result from internal bindings bugs,
-compromised processes, or some remote endpoint making a dubious effort to
-manually encode their own bindings messages.
-
-### Custom Validation
-
-It's also possible for developers to define custom validation logic for specific
-Mojom struct types by exploiting the
-[type mapping](/mojo/public/cpp/bindings/README.md#Type-Mapping) system for C++
-bindings. Messages rejected by custom validation logic trigger the same
-validation failure behavior as the built-in type validation routines.
-
-## Associated Interfaces
-
-As mentioned in the [Primitive Types](#Primitive-Types) section above, pending_remote
-and pending_receiver fields and parameters may be marked as `associated`. This
-essentially means that they are piggy-backed on some other interface's message
-pipe.
-
-Because individual interface message pipes operate independently there can be no
-relative ordering guarantees among them. Associated interfaces are useful when
-one interface needs to guarantee strict FIFO ordering with respect to one or
-more other interfaces, as they allow interfaces to share a single pipe.
-
-Currently associated interfaces are only supported in generated C++ bindings.
-See the documentation for
-[C++ Associated Interfaces](/mojo/public/cpp/bindings/README.md#Associated-Interfaces).
-
-## Versioning
-
-### Overview
-
-*** note
-**NOTE:** You don't need to worry about versioning if you don't care about
-backwards compatibility. Today, all parts of the Chrome browser are
-updated atomically and there is not yet any possibility of any two
-Chrome processes communicating with two different versions of any given Mojom
-interface. On Chrome OS, there are several places where versioning is required.
-For example,
-[ARC++](https://developer.android.com/chrome-os/intro)
-uses versioned mojo to send IPC to the Android container.
-Likewise, the
-[Lacros](/docs/lacros.md)
-browser uses versioned mojo to talk to the ash system UI.
-***
-
-Services extend their interfaces to support new features over time, and clients
-want to use those new features when they are available. If services and clients
-are not updated at the same time, it's important for them to be able to
-communicate with each other using different snapshots (versions) of their
-interfaces.
-
-This document shows how to extend Mojom interfaces in a backwards-compatible
-way. Changing interfaces in a non-backwards-compatible way is not discussed,
-because in that case communication between different interface versions is
-impossible anyway.
-
-### Versioned Structs
-
-You can use the `MinVersion` [attribute](#Attributes) to indicate from which
-version a struct field is introduced. Assume you have the following struct:
-
-``` cpp
-struct Employee {
-  uint64 employee_id;
-  string name;
-};
-```
-
-and you would like to add birthday and nickname fields. You can add them as
-optional types with a `MinVersion` like so:
-
-``` cpp
-struct Employee {
-  uint64 employee_id;
-  string name;
-  [MinVersion=1] Date? birthday;
-  [MinVersion=1] string? nickname;
-};
-```
-
-*** note
-**NOTE:** Mojo object or handle types added with a `MinVersion` **MUST** be
-optional (nullable) or primitive. See [Primitive Types](#Primitive-Types) for
-details on nullable values.
-***
-
-By default, fields belong to version 0. New fields must be appended to the
-struct definition (*i.e*., existing fields must not change **ordinal value**)
-with the `MinVersion` attribute set to a number greater than any previous
-existing versions.
-
-The value of `MinVersion` is unrelated to ordinals. The choice of a particular
-version number is arbitrary. All its usage means is that a field isn't present
-before the numbered version.
-
-*** note
-**NOTE:** do not change existing fields in versioned structs, as this is
-not backwards-compatible. Instead, rename the old field to make its
-deprecation clear and add a new field with a new `MinVersion` number.
-***
-
-**Ordinal value** refers to the relative positional layout of a struct's fields
-(and an interface's methods) when encoded in a message. Implicitly, ordinal
-numbers are assigned to fields according to lexical position. In the example
-above, `employee_id` has an ordinal value of 0 and `name` has an ordinal value
-of 1.
-
-Ordinal values can be specified explicitly using `**@**` notation, subject to
-the following hard constraints:
-
-* For any given struct or interface, if any field or method explicitly specifies
-    an ordinal value, all fields or methods must explicitly specify an ordinal
-    value.
-* For an *N*-field struct, the set of explicitly assigned ordinal values must be
-    limited to the range *[0, N-1]*. Structs should include placeholder fields
-    to fill the ordinal positions of removed fields (for example "Unused_Field"
-    or "RemovedField", etc).
-
-You may reorder fields, but you must ensure that the ordinal values of existing
-fields remain unchanged. For example, the following struct remains
-backwards-compatible:
-
-``` cpp
-struct Employee {
-  uint64 employee_id@0;
-  [MinVersion=1] Date? birthday@2;
-  string name@1;
-  [MinVersion=1] string? nickname@3;
-};
-```
-
-### Versioned Interfaces
-
-There are two dimensions on which an interface can be extended
-
-**Appending New Parameters To Existing Methods**
-:   Parameter lists are treated as structs internally, so all the rules of
-    versioned structs apply to method parameter lists. The only difference is
-    that the version number is scoped to the whole interface rather than to any
-    individual parameter list.
-
-``` cpp
-// Old version:
-interface HumanResourceDatabase {
-  QueryEmployee(uint64 id) => (Employee? employee);
-};
-
-// New version:
-interface HumanResourceDatabase {
-  QueryEmployee(uint64 id, [MinVersion=1] bool retrieve_finger_print)
-      => (Employee? employee,
-          [MinVersion=1] array<uint8>? finger_print);
-};
-```
-
-Similar to [versioned structs](#Versioned-Structs), when you pass the parameter
-list of a request or response method to a destination using an older version of
-an interface, unrecognized fields are silently discarded.
-
-    Please note that adding a response to a message which did not previously
-    expect a response is a not a backwards-compatible change.
-
-**Appending New Methods**
-:   Similarly, you can reorder methods with explicit ordinal values as long as
-    the ordinal values of existing methods are unchanged.
-
-For example:
-
-``` cpp
-// Old version:
-interface HumanResourceDatabase {
-  QueryEmployee(uint64 id) => (Employee? employee);
-};
-
-// New version:
-interface HumanResourceDatabase {
-  QueryEmployee(uint64 id) => (Employee? employee);
-
-  [MinVersion=1]
-  AttachFingerPrint(uint64 id, array<uint8> finger_print)
-      => (bool success);
-};
-```
-
-If a method call is not recognized, it is considered a validation error and the
-receiver will close its end of the interface pipe. For example, if a client on
-version 1 of the above interface sends an `AttachFingerPrint` request to an
-implementation of version 0, the client will be disconnected.
-
-Bindings target languages that support versioning expose means to query or
-assert the remote version from a client handle (*e.g.*, an
-`mojo::Remote<T>` in C++ bindings.)
-
-See
-[C++ Versioning Considerations](/mojo/public/cpp/bindings/README.md#Versioning-Considerations)
-and
-[Java Versioning Considerations](/mojo/public/java/bindings/README.md#Versioning-Considerations)
-
-### Versioned Enums
-
-**By default, enums are non-extensible**, which means that generated message
-validation code does not expect to see new values in the future. When an unknown
-value is seen for a non-extensible enum field or parameter, a validation error
-is raised.
-
-If you want an enum to be extensible in the future, you can apply the
-`[Extensible]` [attribute](#Attributes):
-
-``` cpp
-[Extensible]
-enum Department {
-  kSales,
-  kDev,
-};
-```
-
-And later you can extend this enum without breaking backwards compatibility:
-
-``` cpp
-[Extensible]
-enum Department {
-  kSales,
-  kDev,
-  [MinVersion=1] kResearch,
-};
-```
-
-*** note
-**NOTE:** For versioned enum definitions, the use of a `[MinVersion]` attribute
-is strictly for documentation purposes. It has no impact on the generated code.
-***
-
-With extensible enums, bound interface implementations may receive unknown enum
-values and will need to deal with them gracefully. See
-[C++ Versioning Considerations](/mojo/public/cpp/bindings/README.md#Versioning-Considerations)
-for details.
-
-### Renaming versioned structs
-It's possible to rename versioned structs by using the `[RenamedFrom]` attribute.
-RenamedFrom
-
-``` cpp
-module asdf.mojom;
-
-// Old version:
-[Stable]
-struct OldStruct {
-};
-
-// New version:
-[Stable, RenamedFrom="asdf.mojom.OldStruct"]
-struct NewStruct {
-};
-```
-
-## Component targets
-
-If there are multiple components depending on the same mojom target within one binary,
-the target will need to be defined as `mojom_component` instead of `mojom`.
-Since `mojom` targets are generated `source_set` targets and `mojom_component` targets
-are generated `component` targets, you would use `mojom_component` in the same cases
-where you would use `component` for non-mojom files.
-*** note
-**NOTE**: by default, components for both blink and non-blink bindings are generated.
-Use the `disable_variants` target parameter to generate only non-blink bindings.
-You can also generate a `source_set` for one of the variants by defining
-[export_*](https://source.chromium.org/chromium/chromium/src/+/main:mojo/public/tools/bindings/mojom.gni;drc=739b9fbce50310c1dd2b59c279cd90a9319cb6e8;l=318)
-parameters for the `mojom_component` target.

-#
-#       DEPRECATED: This is synonymous with public_deps because all mojom
-#       dependencies must be public by design. Please use public_deps.
-#
-#   public_deps (optional)
-#       Note: this can contain only other mojom targets.
-#
-#   parser_deps (optional)
-#       List of non-mojom targets required for the mojom sources to be parsed.
-#
-#   import_dirs (optional)
-#       List of import directories that will get added when processing sources.
-#
-#   input_root_override (optional)
-#       Root path for the .mojom files used to generate the namespaces for
-#       interfaces. Useful with targets outside //, e.g. in parent directories
-#       above "//". The default input root is //
-#       Example: Vivaldi's source root is "//vivaldi/",
-#       and "//vivaldi/chromium/" is "//"
-#       In such cases, not using this argument lead to the output files being
-#       located in different directories than expected.
-#
-#   testonly (optional)
-#
-#   visibility (optional)
-#
-#   visibility_blink (optional)
-#       The value to use for visibility for the blink variant. If unset,
-#       |visibility| is used.
-#
-#   cpp_only (optional)
-#       If set to true, only the C++ bindings targets will be generated.
-#
-#       NOTE: If the global |enable_mojom_fuzzer| build arg is true, JS bindings
-#       will still be generated even when |cpp_only| is set to |true|, unless
-#       you also set |enable_fuzzing| to |false| in your mojom target.
-#
-#   cpp_typemaps (optional)
-#       A list of typemaps to be applied to the generated C++ bindings for this
-#       mojom target. Note that this only applies to the non-Blink variant of
-#       generated C++ bindings.
-#
-#       Every typemap is a GN scope describing how one or more mojom types maps
-#       to a non-mojom C++ type, including necessary deps and headers required
-#       for the mapping to work. See the Typemaps section below.
-#
-#   blink_cpp_typemaps (optional)
-#       Same as above, but for the Blink variant of generated C++ bindings.
-#
-#   cpp_proxy_target (optional)
-#       The name of a target which all C++ dependencies will link against
-#       instead of linking directly against this mojom target's generated C++
-#       sources. Normally when declaring invoking the mojom("foo") target, GN
-#       emits a source_set or component target named "foo" which encompasses the
-#       default variant of generated C++ bindings. This changes that to instead
-#       emit a group("foo") which merely forwards public_deps to the named
-#       `cpp_proxy_target`. That target must in turn depend on
-#       "foo_cpp_sources".
-#
-#       This is useful primarily in conjunction with export_define et al to
-#       embed generated C++ bindings within an existing component target.
-#
-#   blink_cpp_proxy_target (optional)
-#       Same concept as `cpp_proxy_target` above, but affects the generated
-#       "foo_blink" Blink-variant C++ bindings.
-#
-#   cpp_configs (optional)
-#       A list of extra configs to apply to the default variant of generated C++
-#       bindings.
-#
-#   blink_cpp_configs (optional)
-#       A list of extra configs to apply to the Blink variant of generated C++
-#       bindings.
-#
-#   mojom_source_deps (optional)
-#       A list of mojoms this target depends upon. This is equivalent to
-#       public_deps except that the C++ bindings depend on each of the named
-#       "foo" targets' "foo_cpp_sources" rather than on foo's
-#       `cpp_proxy_target`. It only makes sense to use this for dependencies
-#       that set `cpp_proxy_target`, and only when the dependent mojom() would
-#       otherwise have circular dependencies with that proxy target.
-#
-#   mojom_blink_source_deps (optional)
-#       Same as above but depends on "foo_blink_cpp_sources" and is used for
-#       dependencies that specify a `blink_cpp_proxy_target`.
-#
-#   generate_java (optional)
-#       If set to true, Java bindings are generated for Android builds. If
-#       |cpp_only| is set to true, it overrides this to prevent generation of
-#       Java bindings.
-#
-#   enable_js_fuzzing (optional)
-#       Enables generation of javascript fuzzing sources for the target if the
-#       global build arg |enable_mojom_fuzzer| is also set to |true|.
-#       Defaults to |true|. If JS fuzzing generation is enabled for a target,
-#       the target will always generate JS bindings even if |cpp_only| is set to
-#       |true|. See note above.
-#
-#   enable_mojolpm_fuzzing (optional)
-#       Enables generation of fuzzing sources for the target if the global build
-#       arg |enable_mojom_fuzzer| is also set to |true|. Defaults to |true|.
-#
-#   support_lazy_serialization (optional)
-#       If set to |true|, generated C++ bindings will effectively prefer to
-#       transmit messages in an unserialized form when going between endpoints
-#       in the same process. This avoids the runtime cost of serialization,
-#       deserialization, and validation logic at the expensive of increased
-#       code size. Defaults to |false|.
-#
-#   disable_variants (optional)
-#       If |true|, no variant sources will be generated for the target. Defaults
-#       to |false|.
-#
-#   disallow_native_types (optional)
-#       If set to |true|, mojoms in this target may not apply the [Native]
-#       attribute to struct or enum declarations. This avoids emitting code
-#       which depends on legacy IPC serialization. Default is |false|, meaning
-#       [Native] types are allowed.
-#
-#   disallow_interfaces (optional)
-#       If set to |true|, mojoms in this target may not define interfaces.
-#       Generates bindings with a smaller set of dependencies. Defaults to
-#       |false|.
-#
-#   scramble_message_ids (optional)
-#       If set to |true| (the default), generated mojom interfaces will use
-#       scrambled ordinal identifiers in encoded messages.
-#
-#   component_output_prefix (optional)
-#       The prefix to use for the output_name of any component library emitted
-#       for generated C++ bindings. If this is omitted, C++ bindings targets are
-#       emitted as source_sets instead. Because this controls the name of the
-#       output shared library binary in the root output directory, it must be
-#       unique across the entire build configuration.
-#
-#       This is required if |component_macro_prefix| is specified.
-#
-#   component_macro_prefix (optional)
-#       This specifies a macro prefix to use for component export macros and
-#       should therefore be globally unique in the project. For example if this
-#       is "FOO_BAR", then the generated C++ sources will be built with
-#       IS_FOO_BAR_{suffix}_IMPL defined, and the generated public headers will
-#       annotate public symbol definitions with
-#       COMPONENT_EXPORT(FOO_BAR_{suffix}). "suffix" in this case depends on
-#       which internal subtarget is generating the code (e.g. "SHARED", or a
-#       variant name like "BLINK").
-#
-#   enabled_features (optional)
-#       Definitions in a mojom file can be guarded by an EnableIf attribute. If
-#       the value specified by the attribute does not match any items in the
-#       list of enabled_features, the definition will be disabled, with no code
-#       emitted for it.
-#
-#   generate_closure_exports (optional)
-#       Generates JS lite bindings will use goog.provide and goog.require
-#       annotations to export its symbols and import core Mojo bindings support
-#       and other mojom dependency modules. Use this if you plan to compile your
-#       bindings into a larger JS binary. Defaults to |false|, instead
-#       generating JS lite bindings which assume they will be manually loaded in
-#       correct dependency order. Note that this only has an effect if
-#       the |enable_mojom_closure_compile| global arg is set to |true| as well.
-#
-#   generate_webui_js_bindings (optional)
-#       Generate WebUI bindings in JavaScript rather than TypeScript. Defaults
-#       to false. ChromeOS only parameter.
-#
-#   generate_legacy_js_bindings (optional)
-#       Generate js_data_deps target containing legacy JavaScript bindings files
-#       for Blink tests and other non-WebUI users when generating TypeScript
-#       bindings for WebUI. Ignored if generate_webui_js_bindings is set to
-#       true.
-#
-#   js_generate_struct_deserializers (optional)
-#       Generates JS deerialize methods for structs.
-#
-#   extra_cpp_template_paths (optional)
-#       List of extra C++ templates that are used to generate additional source
-#       and/or header files. The templates should end with extension ".tmpl".
-#
-#   webui_module_path (optional)
-#       The path or URL at which modules generated by this target will be
-#       accessible to WebUI pages. This may either be an absolute path or
-#       a full URL path starting with "chrome://resources/mojo". If this path
-#       is not specified, WebUI bindings will not be generated.
-#
-#       If an absolute path, a WebUI page may only import these modules if
-#       they are added to that page's data source (usually by adding the
-#       modules to the mojo_files list for build_webui(), or by listing the
-#       files as inputs to the page's ts_library() and/or generate_grd() build
-#       steps.
-#
-#       If this is is instead a URL string starting with
-#       "chrome://resources/mojo", the resulting bindings files should
-#       be added to one of the lists in ui/webui/resources/mojo/BUILD.gn,
-#       at which point they will be made available to all WebUI pages at the
-#       given URL.
-#
-#       Note: WebUI module bindings are generated in TypeScript by default,
-#       unless |generate_webui_js_bindings| is specified as true.
-#
-# The following parameters are used to support the component build. They are
-# needed so that bindings which are linked with a component can use the same
-# export settings for classes. The first three are for the chromium variant, and
-# the last three are for the blink variant. These parameters can also override
-# |component_macro_prefix| for a specific variant, allowing e.g. one variant
-# to be linked into a larger non-mojom component target, while all other
-# variants get their own unique component target.
-#   export_class_attribute (optional)
-#       The attribute to add to the class declaration. e.g. "CONTENT_EXPORT"
-#   export_define (optional)
-#       A define to be added to the source_set which is needed by the export
-#       header. e.g. "CONTENT_IMPLEMENTATION=1"
-#   export_header (optional)
-#       A header to be added to the generated bindings to support the component
-#       build. e.g. "content/common/content_export.h"
-#   export_class_attribute_blink (optional)
-#   export_define_blink (optional)
-#   export_header_blink (optional)
-#       These three parameters are the blink variants of the previous 3.
-#
-# The following parameters are used to correct component build dependencies.
-# They are needed so mojom-mojom dependencies follow the rule that dependencies
-# on a source set in another component are replaced by a dependency on the
-# containing component. The first two are for the chromium variant; the other
-# two are for the blink variant.
-#   overridden_deps (optional)
-#       The list of mojom deps to be overridden.
-#   component_deps (optional)
-#       The list of component deps to add to replace overridden_deps.
-#   overridden_deps_blink (optional)
-#   component_deps_blink (optional)
-#       These two parameters are the blink variants of the previous two.
-#
-#   check_includes_blink (optional)
-#       Overrides the check_includes variable for the blink variant.
-#       If check_includes_blink is not defined, the check_includes variable
-#       retains its original value.
-#
-# Typemaps
-# ========
-# The cpp_typemaps and blink_cpp_typemaps each specify an optional list of
-# typemapping configurations. Each configuration is a GN scope with metadata
-# describing what and how to map.
-#
-# Typemap scope parameters:
-#   types
-#       A list of type specifications for this typemap. Each type specification
-#       is a nested GN scope which can be expressed with the following syntax:
-#
-#           {
-#             mojom = "foo.mojom.Bar"
-#             cpp = "::foo::LegitBar"
-#             move_only = true
-#             # etc...
-#           }
-#
-#       Each type specification supports the following values:
-#
-#         mojom (required)
-#             The fully qualified name of a mojom type to be mapped. This is a
-#             string like "foo.mojom.Bar".
-#
-#         cpp (required)
-#             The fully qualified name of the C++ type to which the mojom type
-#             should be mapped in generated bindings. This is a string like
-#             "::base::Value" or "std::vector<::base::Value>".
-#
-#         copyable_pass_by_value (optional)
-#             A boolean value (default false) which effectively indicates
-#             whether the C++ type is very cheap to copy. If so, generated
-#             bindings will pass by value but not use std::move() at call sites.
-#
-#         default_constructible (optional)
-#             A boolean value (default true) which indicates whether the C++
-#             type is default constructible. If a C++ type is not default
-#             constructible (e.g. the implementor of the type prefers not to
-#             publicly expose a default constructor that creates an object in an
-#             invalid state), Mojo will instead construct C++ type with an
-#             argument of the type `mojo::DefaultConstruct::Tag` (essentially a
-#             passkey-like type specifically for this use case).
-#
-#         force_serialize (optional)
-#             A boolean value (default false) which disables lazy serialization
-#             of the typemapped type if lazy serialization is enabled for the
-#             mojom target applying this typemap.
-#
-#         forward_declaration (optional)
-#             A forward declaration of the C++ type, which bindings that don't
-#             need the full type definition can use to reduce the size of
-#             the generated code. This is a string like
-#             "namespace base { class Value; }".
-#
-#         hashable (optional)
-#             A boolean value (default false) indicating whether the C++ type is
-#             hashable. Set to true if true AND needed (i.e. you need to use the
-#             type as the key of a mojom map).
-#
-#         move_only (optional)
-#             A boolean value (default false) which indicates whether the C++
-#             type is move-only. If true, generated bindings will pass the type
-#             by value and use std::move() at call sites.
-#
-#         nullable_is_same_type (optional)
-#             A boolean value (default false) which indicates that the C++ type
-#             has some baked-in semantic notion of a "null" state. If true, the
-#             traits for the type must define IsNull and SetToNull methods.
-#
-#             When false, nullable fields are represented by wrapping the C++
-#             type with absl::optional, and null values are simply
-#             absl::nullopt.
-#
-# Additional typemap scope parameters:
-#
-#   traits_headers (optional)
-#       Headers which must be included in the generated mojom in order for
-#       serialization to be possible. This generally means including at least
-#       the header for the corresponding mojom traits definitions.
-#
-#   traits_private_headers (optional)
-#       Headers which must be included in generated C++ serialization code for
-#       a mojom using the typemap. This should be used only when including a
-#       header in |traits_headers| is problematic for compilation, as is
-#       sometimes the case with legacy IPC message headers.
-#
-#   traits_sources (optional)
-#       The references to the source files (typically a single .cc and .h file)
-#       defining an appropriate set of EnumTraits or StructTraits, etc for the
-#       the type-mapping. Using this will cause the listed sources to be
-#       integrated directly into the dependent mojom's generated type-mapping
-#       targets.
-#
-#       Prefer using |traits_public_deps| over inlined |traits_sources|, as this
-#       will generally lead to easier build maintenance over time.
-#
-#       NOTE: If a typemap is shared by Blink and non-Blink bindings, you cannot
-#       use this and MUST use |traits_public_deps| to reference traits built
-#       within a separate target.
-#
-#   traits_deps / traits_public_deps (optional)
-#       Any dependencies of sources in |traits_headers| or |traits_sources| must
-#       be listed here.
