+// `HttpRule` defines the mapping of an RPC method to one or more HTTP REST API
+// methods. The mapping determines what portions of the request message are
+// populated from the path, query parameters, or body of the HTTP request.  The
+// mapping is typically specified as an `google.api.http` annotation, see
+// "google/api/annotations.proto" for details.
+//
+// The mapping consists of a mandatory field specifying a path template and an
+// optional `body` field specifying what data is represented in the HTTP request
+// body. The field name for the path indicates the HTTP method. Example:
+//
+// ```
+// package google.storage.v2;
+//
+// import "google/api/annotations.proto";
+//
+// service Storage {
+//   rpc CreateObject(CreateObjectRequest) returns (Object) {
+//     option (google.api.http) {
+//       post: "/v2/{bucket_name=buckets/*}/objects"
+//       body: "object"
+//     };
+//   };
+// }
+// ```
+//
+// Here `bucket_name` and `object` bind to fields of the request message
+// `CreateObjectRequest`.
+//
+// The rules for mapping HTTP path, query parameters, and body fields
+// to the request message are as follows:
+//
+// 1. The `body` field specifies either `*` or a field path, or is
+//    omitted. If omitted, it assumes there is no HTTP body.
+// 2. Leaf fields (recursive expansion of nested messages in the
+//    request) can be classified into three types:
+//     (a) Matched in the URL template.
+//     (b) Covered by body (if body is `*`, everything except (a) fields;
+//         else everything under the body field)
+//     (c) All other fields.
+// 3. URL query parameters found in the HTTP request are mapped to (c) fields.
+// 4. Any body sent with an HTTP request can contain only (b) fields.
+//
+// The syntax of the path template is as follows:
+//
+//     Template = "/" Segments [ Verb ] ;
+//     Segments = Segment { "/" Segment } ;
+//     Segment  = "*" | "**" | LITERAL | Variable ;
+//     Variable = "{" FieldPath [ "=" Segments ] "}" ;
+//     FieldPath = IDENT { "." IDENT } ;
+//     Verb     = ":" LITERAL ;
+//
+// `*` matches a single path component, `**` zero or more path components, and
+// `LITERAL` a constant.  A `Variable` can match an entire path as specified
+// again by a template; this nested template must not contain further variables.
+// If no template is given with a variable, it matches a single path component.
+// The notation `{var}` is henceforth equivalent to `{var=*}`.
+//
+// Use CustomHttpPattern to specify any HTTP method that is not included in the
+// pattern field, such as HEAD, or "*" to leave the HTTP method unspecified for
+// a given URL path rule. The wild-card rule is useful for services that provide
+// content to Web (HTML) clients.
+message HttpRule {
+
+  // Determines the URL pattern is matched by this rules. This pattern can be
+  // used with any of the {get|put|post|delete|patch} methods. A custom method
+  // can be defined using the 'custom' field.
+  oneof pattern {
+    // Used for listing and getting information about resources.
