      # # 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.

        # 5.3` would mean "5300 page views per day"). * `%` represents dimensionless
        # value of 1/100, and annotates values giving a percentage (so the metric values
        # are typically in the range of 0..100, and a metric value `3` means "3 percent")
