// option objc_class_prefix = "HLW";

package com.zwp.grpc.test;

// The greeting service definition.
service TestGreeter {
  // Sends a greeting
  rpc SayHello (Person) returns (Reply) {}

  rpc Addition (Number) returns (Result) {}
}

// The request message containing the user's name.
message Person {
  string name = 1;
  string speak = 2;
}

// The response message containing the greetings
message Reply {
  string message = 1;
}

message Number {
  int32 one = 1;
  int32 two = 2;
}

message Result {
  int32 result = 1;
}
