The correct definition of service in .proto file

[王迁]

There are two kind of service definition in grpc official guide,

one is:

service HelloService {
  rpc SayHello (HelloRequest) returns (HelloResponse); // end with ;
}

and the other is:

service HelloService {
  rpc SayHello (HelloRequest) returns (HelloResponse) {} // end with {}
}

Is there some difference between them?

Thanks!

Hi,

You can add service options inside {  }. See https://developers.google.com/protocol-buffers/docs/proto3#options (if you don't know what message, service etc. options are, chances are you can safely ignore they exist).

Thanks Jan, I read doc about options and the file descriptor.proto. It seems quite an advance usage and I choose to ignore them ^_^.
