      # 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: `GET /v1/messages/123456` - gRPC: `
      # 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: `GET /v1/messages/123456?
      # revision=2&sub.subfield=foo` - gRPC: `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: `PATCH /v1/messages/123456 ` "text": "Hi!" `` - gRPC: `
      # 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: `PATCH /v1/messages/123456 ` "text": "Hi!" `` - gRPC: `
      # 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: `GET /
      # v1/messages/123456` - gRPC: `GetMessage(message_id: "123456")` - HTTP: `GET /
      # v1/users/me/messages/123456` - gRPC: `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. The following example selects a gRPC method and applies an `
      # HttpRule` to it: http: rules: - 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.

        # ucum.html) standard: **Basic units (UNIT)** * `bit` bit * `By` byte * `s`
        # second * `min` minute * `h` hour * `d` day * `1` dimensionless **Prefixes (
        # PREFIX)** * `k` kilo (10^3) * `M` mega (10^6) * `G` giga (10^9) * `T` tera (10^
        # 12) * `P` peta (10^15) * `E` exa (10^18) * `Z` zetta (10^21) * `Y` yotta (10^

        # 2^40) * `Pi` pebi (2^50) **Grammar** The grammar also includes these
        # connectors: * `/` division or ratio (as an infix operator). For examples, `kBy/
        # `email`` or `MiBy/10ms` (although you should almost never have `/s` in a
        # metric `unit`; rates should always be computed at query time from the
        # underlying cumulative or delta value). * `.` multiplication or composition (as
        # an infix operator). For examples, `GBy.d` or `k`watt`.h`. The grammar for a
        # unit is as follows: Expression = Component ` "." Component ` ` "/" Component `
        # ; Component = ( [ PREFIX ] UNIT | "%" ) [ Annotation ] | Annotation | "1" ;
        # Annotation = "`" NAME "`" ; Notes: * `Annotation` is just a comment if it
        # follows a `UNIT`. If the annotation is used alone, then the unit is equivalent
        # to `1`. For examples, ``request`/s == 1/s`, `By`transmitted`/s == By/s`. * `
        # NAME` is a sequence of non-blank printable ASCII characters not containing ```
        # or ```. * `1` represents a unitary [dimensionless unit](https://en.wikipedia.
        # org/wiki/Dimensionless_quantity) of 1, such as in `1/s`. It is typically used
        # when none of the basic units are appropriate. For example, "new users per day"
        # can be represented as `1/d` or ``new-users`/d` (and a metric value `5` would
        # mean "5 new users). Alternatively, "thousands of page views per day" would be
        # represented as `1000/d` or `k1/d` or `k`page_views`/d` (and a metric value of `
        # 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")
        # . * `10^2.%` indicates a metric contains a ratio, typically in the range 0..1,
        # that will be multiplied by 100 and displayed as a percentage (so a metric
        # value `0.03` means "3 percent").
