-/// # 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

+/// 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/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
+/// "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

+/// 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
+/// `{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

-/// ## 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
+/// `{+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
+/// 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
+/// 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).
