-# Editing this README
-
-When you're ready to make this README your own, just edit this file and use the handy template below (or feel free to structure it however you want - this is just a starting point!). Thank you to [makeareadme.com](https://www.makeareadme.com/) for this template.
-
-## Suggestions for a good README
-Every project is different, so consider which of these sections apply to yours. The sections used in the template are suggestions for most open source projects. Also keep in mind that while a README can be too long and detailed, too long is better than too short. If you think your README is too long, consider utilizing another form of documentation rather than cutting out information.
-
-## Name
-Choose a self-explaining name for your project.
-
-## Description
-Let people know what your project can do specifically. Provide context and add a link to any reference visitors might be unfamiliar with. A list of Features or a Background subsection can also be added here. If there are alternatives to your project, this is a good place to list differentiating factors.
-
-## Badges
-On some READMEs, you may see small images that convey metadata, such as whether or not all the tests are passing for the project. You can use Shields to add some to your README. Many services also have instructions for adding a badge.
-
-## Visuals
-Depending on what you are making, it can be a good idea to include screenshots or even a video (you'll frequently see GIFs rather than actual videos). Tools like ttygif can help, but check out Asciinema for a more sophisticated method.
-
-## Installation
-Within a particular ecosystem, there may be a common way of installing things, such as using Yarn, NuGet, or Homebrew. However, consider the possibility that whoever is reading your README is a novice and would like more guidance. Listing specific steps helps remove ambiguity and gets people to using your project as quickly as possible. If it only runs in a specific context like a particular programming language version or operating system or has dependencies that have to be installed manually, also add a Requirements subsection.
-
-## Usage
-Use examples liberally, and show the expected output if you can. It's helpful to have inline the smallest example of usage that you can demonstrate, while providing links to more sophisticated examples if they are too long to reasonably include in the README.
-
-## Support
-Tell people where they can go to for help. It can be any combination of an issue tracker, a chat room, an email address, etc.
-
-## Roadmap
-If you have ideas for releases in the future, it is a good idea to list them in the README.
-
-## Contributing
-State if you are open to contributions and what your requirements are for accepting them.
-
-For people who want to make changes to your project, it's helpful to have some documentation on how to get started. Perhaps there is a script that they should run or some environment variables that they need to set. Make these steps explicit. These instructions could also be useful to your future self.
-
-You can also document commands to lint the code or run tests. These steps help to ensure high code quality and reduce the likelihood that the changes inadvertently break something. Having instructions for running tests is especially helpful if it requires external setup, such as starting a Selenium server for testing in a browser.
-
-## Authors and acknowledgment
-Show your appreciation to those who have contributed to the project.
-
-## License
-For open source projects, say how it is licensed.
-
-## Project status
-If you have run out of energy or time for your project, put a note at the top of the README saying that development has slowed down or stopped completely. Someone may choose to fork your project or volunteer to step in as a maintainer or owner, allowing your project to keep going. You can also make an explicit request for maintainers.

+// # 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 {

+// `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.
