      # # gRPC Transcoding
      # gRPC Transcoding is a feature for mapping between a gRPC method and one or
      # more HTTP REST endpoints. It allows developers to build a single API service
      # that supports both gRPC APIs and REST APIs. Many systems, including [Google
      # APIs](https://github.com/googleapis/googleapis),
      # [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
      # Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
      # and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
      # and use it for large scale production services.
      # `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
      # how different portions of the gRPC request message are mapped to the URL
      # path, URL query parameters, and HTTP request body. It also controls how the
      # gRPC response message is mapped to the HTTP response body. `HttpRule` is
      # typically specified as an `google.api.http` annotation on the gRPC method.
      # Each mapping specifies a URL path template and an HTTP method. The path
      # template may refer to one or more fields in the gRPC request message, as long
      # as each field is a non-repeated field with a primitive (non-message) type.
      # The path template controls how fields of the request message are mapped to
      # the URL path.
      # Example:
      # service Messaging `
      # rpc GetMessage(GetMessageRequest) returns (Message) `
      # option (google.api.http) = `
      # get: "/v1/`name=messages/*`"
      # `;
      # `
      # `
      # message GetMessageRequest `
      # string name = 1; // Mapped to URL path.
      # `
      # message Message `
      # string text = 1; // The resource content.
      # `
      # This enables an HTTP REST to gRPC mapping as below:
      # HTTP | gRPC
      # -----|-----
      # `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
      # Any fields in the request message which are not bound by the path template
      # automatically become HTTP query parameters if there is no HTTP request body.
      # For example:
      # service Messaging `
      # rpc GetMessage(GetMessageRequest) returns (Message) `
      # option (google.api.http) = `
      # get:"/v1/messages/`message_id`"
      # `;
      # `
      # `
      # message GetMessageRequest `
      # message SubMessage `
      # string subfield = 1;
      # `
      # string message_id = 1; // Mapped to URL path.
      # int64 revision = 2;    // Mapped to URL query parameter `revision`.
      # SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
      # `
      # This enables a HTTP JSON to RPC mapping as below:
      # HTTP | gRPC
      # -----|-----
      # `GET /v1/messages/123456?revision=2&sub.subfield=foo` | `GetMessage(message_id:
      # "123456" revision: 2 sub: SubMessage(subfield: "foo"))`
      # Note that fields which are mapped to URL query parameters must have a
      # primitive type or a repeated primitive type or a non-repeated message type.
      # In the case of a repeated type, the parameter can be repeated in the URL
      # as `...?param=A&param=B`. In the case of a message type, each field of the
      # message is mapped to a separate parameter, such as
      # `...?foo.a=A&foo.b=B&foo.c=C`.
      # For HTTP methods that allow a request body, the `body` field
      # specifies the mapping. Consider a REST update method on the
      # message resource collection:
      # service Messaging `
      # rpc UpdateMessage(UpdateMessageRequest) returns (Message) `
      # option (google.api.http) = `
      # patch: "/v1/messages/`message_id`"
      # body: "message"
      # `;
      # `
      # `
      # message UpdateMessageRequest `
      # string message_id = 1; // mapped to the URL
      # Message message = 2;   // mapped to the body
      # `
      # The following HTTP JSON to RPC mapping is enabled, where the
      # representation of the JSON in the request body is determined by
      # protos JSON encoding:
      # HTTP | gRPC
      # -----|-----
      # `PATCH /v1/messages/123456 ` "text": "Hi!" `` | `UpdateMessage(message_id: "
      # 123456" message ` text: "Hi!" `)`
      # The special name `*` can be used in the body mapping to define that
      # every field not bound by the path template should be mapped to the
      # request body.  This enables the following alternative definition of
      # the update method:
      # service Messaging `
      # rpc UpdateMessage(Message) returns (Message) `
      # option (google.api.http) = `
      # patch: "/v1/messages/`message_id`"
      # body: "*"
      # `;
      # `
      # `
      # message Message `
      # string message_id = 1;
      # string text = 2;
      # `
      # The following HTTP JSON to RPC mapping is enabled:
      # HTTP | gRPC
      # -----|-----
      # `PATCH /v1/messages/123456 ` "text": "Hi!" `` | `UpdateMessage(message_id: "
      # 123456" text: "Hi!")`
      # Note that when using `*` in the body mapping, it is not possible to
      # have HTTP parameters, as all fields not bound by the path end in
      # the body. This makes this option more rarely used in practice when
      # defining REST APIs. The common usage of `*` is in custom methods
      # which don't use the URL at all for transferring data.
      # It is possible to define multiple HTTP methods for one RPC by using
      # the `additional_bindings` option. Example:
      # service Messaging `
      # rpc GetMessage(GetMessageRequest) returns (Message) `
      # option (google.api.http) = `
      # get: "/v1/messages/`message_id`"
      # additional_bindings `
      # get: "/v1/users/`user_id`/messages/`message_id`"
      # `
      # `;
      # `
      # `
      # message GetMessageRequest `
      # string message_id = 1;
      # string user_id = 2;
      # `
      # This enables the following two alternative HTTP JSON to RPC mappings:
      # HTTP | gRPC
      # -----|-----
      # `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
      # `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id: "
      # 123456")`
      # ## Rules for HTTP mapping
      # 1. Leaf request fields (recursive expansion nested messages in the request
      # message) are classified into three categories:
      # - Fields referred by the path template. They are passed via the URL path.
      # - Fields referred by the HttpRule.body. They are passed via the HTTP
      # request body.
      # - All other fields are passed via the URL query parameters, and the
      # parameter name is the field path in the request message. A repeated
      # field can be represented as multiple query parameters under the same
      # name.
      # 2. If HttpRule.body is "*", there is no URL query parameter, all fields
      # are passed via URL path and HTTP request body.
      # 3. If HttpRule.body is omitted, there is no HTTP request body, all
      # fields are passed via URL path and URL query parameters.
      # ### Path template syntax
      # Template = "/" Segments [ Verb ] ;
      # Segments = Segment ` "/" Segment ` ;
      # Segment  = "*" | "**" | LITERAL | Variable ;
      # Variable = "`" FieldPath [ "=" Segments ] "`" ;
      # FieldPath = IDENT ` "." IDENT ` ;
      # Verb     = ":" LITERAL ;
      # The syntax `*` matches a single URL path segment. The syntax `**` matches
      # zero or more URL path segments, which must be the last part of the URL path
      # except the `Verb`.
      # The syntax `Variable` matches part of the URL path as specified by its
      # template. A variable template must not contain other variables. If a variable
      # matches a single path segment, its template may be omitted, e.g. ``var``
      # is equivalent to ``var=*``.
      # The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
      # contains any reserved character, such characters should be percent-encoded
      # before the matching.
      # If a variable contains exactly one path segment, such as `"`var`"` or
      # `"`var=*`"`, when such a variable is expanded into a URL path on the client
      # side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
      # server side does the reverse decoding. Such variables show up in the
      # [Discovery Document](https://developers.google.com/discovery/v1/reference/apis)
      # as ``var``.
      # If a variable contains multiple path segments, such as `"`var=foo/*`"`
      # or `"`var=**`"`, when such a variable is expanded into a URL path on the
      # client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
      # The server side does the reverse decoding, except "%2F" and "%2f" are left
      # unchanged. Such variables show up in the
      # [Discovery Document](https://developers.google.com/discovery/v1/reference/apis)
      # as ``+var``.
      # ## Using gRPC API Service Configuration
      # gRPC API Service Configuration (service config) is a configuration language
      # for configuring a gRPC service to become a user-facing product. The
      # service config is simply the YAML representation of the `google.api.Service`
      # proto message.
      # As an alternative to annotating your proto file, you can configure gRPC
      # transcoding in your service config YAML files. You do this by specifying a
      # `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
      # effect as the proto annotation. This can be particularly useful if you
      # have a proto that is reused in multiple services. Note that any transcoding
      # specified in the service config will override any matching transcoding
      # configuration in the proto.
      # Example:
      # http:
      # rules:
      # # Selects a gRPC method and applies HttpRule to it.
      # - selector: example.v1.Messaging.GetMessage
      # get: /v1/messages/`message_id`/`sub.subfield`
      # ## Special notes
      # When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
      # proto to JSON conversion must follow the [proto3
      # specification](https://developers.google.com/protocol-buffers/docs/proto3#json)
      # .
      # While the single segment variable follows the semantics of
      # [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
      # Expansion, the multi segment variable **does not** follow RFC 6570 Section
      # 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
      # does not expand special characters like `?` and `#`, which would lead
      # to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
      # for multi segment variables.
      # The path variables **must not** refer to any repeated or mapped field,
      # because client libraries are not capable of handling such variable expansion.
      # The path variables **must not** capture the leading "/" character. The reason
      # is that the most common use case "`var`" does not capture the leading "/"
      # character. For consistency, all path variables must share the same behavior.
      # Repeated message fields must not be mapped to URL query parameters, because
      # no client library can support such complicated mapping.
      # If an API needs to use a JSON array for request or response body, it can map
      # the request or response body to a repeated field. However, some gRPC
      # Transcoding implementations may not support this feature.

      # The mixin construct implies that all methods in `AccessControl` are

        # [gRPC](https://github.com/grpc). The error model is designed to be:
        # - Simple to use and understand for most users
        # - Flexible enough to meet unexpected needs
        # # Overview
        # The `Status` message contains three pieces of data: error code, error message,
        # and error details. The error code should be an enum value of
        # google.rpc.Code, but it may accept additional error codes if needed.  The
        # error message should be a developer-facing English message that helps
        # developers *understand* and *resolve* the error. If a localized user-facing
        # error message is needed, put the localized message in the error details or
        # localize it in the client. The optional error details may contain arbitrary
        # information about the error. There is a predefined set of error detail types
        # in the package `google.rpc` that can be used for common error conditions.
        # # Language mapping
        # The `Status` message is the logical representation of the error model, but it
        # is not necessarily the actual wire format. When the `Status` message is
        # exposed in different client libraries and different wire protocols, it can be
        # mapped differently. For example, it will likely be mapped to some exceptions
        # in Java, but more likely mapped to some error codes in C.
        # # Other uses
        # The error model and the `Status` message can be used in a variety of
        # environments, either with or without APIs, to provide a
        # consistent developer experience across different environments.
        # Example uses of this error model include:
        # - Partial errors. If a service needs to return partial errors to the client,
        # it may embed the `Status` in the normal response to indicate the partial
        # errors.
        # - Workflow errors. A typical workflow has multiple steps. Each step may
        # have a `Status` message for error reporting.
        # - Batch operations. If a client uses batch request and batch response, the
        # `Status` message should be used directly inside batch response, one for
        # each error sub-response.
        # - Asynchronous operations. If an API call embeds asynchronous operation
        # results in its response, the status of those operations should be
        # represented directly using the `Status` message.
        # - Logging. If some API errors are stored in logs, the message `Status` could
        # be used directly after any stripping needed for security/privacy reasons.

      # The `Status` type defines a logical error model that is suitable for different
      # programming environments, including REST APIs and RPC APIs. It is used by
      # [gRPC](https://github.com/grpc). The error model is designed to be:
      # - Simple to use and understand for most users
      # - Flexible enough to meet unexpected needs
      # # Overview
      # The `Status` message contains three pieces of data: error code, error message,
      # and error details. The error code should be an enum value of
      # google.rpc.Code, but it may accept additional error codes if needed.  The
      # error message should be a developer-facing English message that helps
      # developers *understand* and *resolve* the error. If a localized user-facing
      # error message is needed, put the localized message in the error details or
      # localize it in the client. The optional error details may contain arbitrary
      # information about the error. There is a predefined set of error detail types
      # in the package `google.rpc` that can be used for common error conditions.
      # # Language mapping
      # The `Status` message is the logical representation of the error model, but it
      # is not necessarily the actual wire format. When the `Status` message is
      # exposed in different client libraries and different wire protocols, it can be
      # mapped differently. For example, it will likely be mapped to some exceptions
      # in Java, but more likely mapped to some error codes in C.
      # # Other uses
      # The error model and the `Status` message can be used in a variety of
      # environments, either with or without APIs, to provide a
      # consistent developer experience across different environments.
      # Example uses of this error model include:
      # - Partial errors. If a service needs to return partial errors to the client,
      # it may embed the `Status` in the normal response to indicate the partial
      # errors.
      # - Workflow errors. A typical workflow has multiple steps. Each step may
      # have a `Status` message for error reporting.
      # - Batch operations. If a client uses batch request and batch response, the
      # `Status` message should be used directly inside batch response, one for
      # each error sub-response.
      # - Asynchronous operations. If an API call embeds asynchronous operation
      # results in its response, the status of those operations should be
      # represented directly using the `Status` message.
      # - Logging. If some API errors are stored in logs, the message `Status` could
      # be used directly after any stripping needed for security/privacy reasons.
