// [gRPC
// Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
// and [Envoy](https://github.com/envoyproxy/envoy) proxy support this

//
// `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)
// a
// s `{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)
// a
// s `{+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.

//
// - Each annotation belonging to the service config (http,
//   visibility) which is not set in the redeclared method will be
//   inherited.
//
// - If an http annotation is inherited, the path pattern will be
//   modified as follows. Any version prefix will be replaced by the
//   version of the including interface plus the root path if
//   specified.
//
// Example of a simple mixin:
//
//     package google.acl.v1;
//     service AccessControl {
//       // Get the underlying ACL object.
//       rpc GetAcl(GetAclRequest) returns (Acl) {

//         option (google.api.http).get = "/v2/{resource=**}";
//       }

// Example of a mixin configuration:
//
//     apis:
//     - name: google.storage.v2.Storage
//       mixins:
//       - name: google.acl.v1.AccessControl
//
// The mixin construct implies that all methods in `AccessControl`
// are
// also declared with same name and request/response types in
// `Storage`. A documentation generator or annotation processor will
// see the effective `Storage.GetAcl` method after
// inherting
// documentation and annotations as follows:
//
//     service Storage {
//       // Get the underlying ACL object.
//       rpc GetAcl(GetAclRequest) returns (Acl) {
//         option (google.api.http).get = "/v2/{resource=**}:getAcl";
//       }
//       ...
//     }
//
// Note how the version in the path pattern changed from `v1` to
// `v2`.
//
// If the `root` field in the mixin is specified, it should be
// a

//
//     apis:
//     - name: google.storage.v2.Storage
//       mixins:
//       - name: google.acl.v1.AccessControl

// Status: 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, 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.
