How to  Pass a a vector  (using repeated in protobuf file) from server to client using stream

The gRPC server client interaction is stream.

//---------------------------STRUCTURE OF PROTO FILE---------------------------------------------------------

message Response

{

int param1 = 20;

int param2 = 30;

float param2 = 30;

}. ..

message ParamResponse

{

repeated Response =20;

}

 // RPC calls from Client to Serve

rpc Read( readyCommand ) returns ( stream ParamResponse ){ }

--------------------------------------------------------------------------------------

In CPP project -

sendDatato Client ( ....  ....,. ..,,,  ParamResponse DataResponse  )

{

typedef std::vector<std::tuple<int,int, float>> Container;

} 

Would like to know how can I pass the container.

Hi, 

It seems like you are looking for help with usage of protobuf for repeated fields. 

protobuf has pretty good documentations for such stuff - https://developers.google.com/protocol-buffers/docs/reference/cpp-generated#repeatedmessage 

Hope that helps. Cheers!
