GoogleProtobufEmpty typedef
        
  
GoogleProtobufEmpty = $Empty
    
    
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 {}.
Implementation
typedef GoogleProtobufEmpty = $Empty;
