-// # 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.

-// 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][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.
