Server Streaming delivery confirmation

[wackazong]

How can I make sure that a client has received a message that is sent to the client in a server streaming response? I want to make sure the message has actually reached the client or otherwise resend it in the stream. I know that I can implement Drop to react to the client disconnecting. I want a handler that is called when a message has been delivered successfully to the client.

You would need to have the client send an ack message back. This isn't something that is supported out of the box with grpc.
