Hello all,
I am implementing a simple client-server grpc-c++ based application. In the 
Hello rpc, I am taking the request and sending the fields of another 
message called SeverInfo as response. The problem is I exactly don't know 
how to send this ServerInfo data to a client from server side. We basically 
use set_fieldname(ex: set_name) for general datatypes to send the data but 
how should we send this serverInfo data to HelloResponse and then to 
HelloRequest. Can somebody please help me??


syntax = "proto3";

package recognizer;

service Recognizer {
   rpc Hello(HelloRequest) returns (HelloResponse){}
}
message HelloRequest {
    string name = 1;
}
message HelloResponse {
    ServerInfo server = 1;
}
message ServerInfo {
    string name = 1;
    string os = 2;
    string arch = 3;
    int32 nproc = 4;
}
