package helloworld;

service Greeter {
  rpc unary (UnaryRequest) returns (UnaryResponse) {}
  rpc serverStreaming (UnaryRequest) returns (stream UnaryResponse) {}
  rpc clientStreaming (stream UnaryRequest) returns (UnaryResponse) {}
  rpc duplexStreaming (stream UnaryRequest) returns (stream UnaryResponse) {}
}
