// A generic empty message that you can re-use to avoid defining duplicated
// empty messages in your APIs. A typical example is to use it as the request
// or the response type of an API method. For instance:
//
//     service Foo {
//       rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);
//     }
//
// The JSON representation for `Empty` is empty JSON object `{}`.
