+// # 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][google.api.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][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
+//     are passed via URL path and HTTP request body.
+//  3. If [HttpRule.body][google.api.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.
