How to write codes in the server when the proto file has more than one services ?

[najcit]

the content of the proto file:

syntax = "proto3";
package helloworld;

// The greeting service definition.
service Greeter {
// Sends a greeting
rpc SayHello (HelloRequest) returns (HelloReply) {}
}

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

// The response message containing the greetings
message HelloReply {
string message = 1;
}
service Talk {
rpc TalkSomething (TalkRequest) returns (TalkReply) {}
}

message TalkRequest {
string name = 1;
}

message TalkReply {
string message = 1;
}

the codes of the server.rs file:
let new_service = server::GreeterServer::new(Greet);

let mut server = Server::new(new_service);

let http = Http::new().http2_only(true).clone();

let addr = "[::1]:50051".parse().unwrap();
let bind = TcpListener::bind(&addr).expect("bind");

let serve = bind
    .incoming()
    .for_each(move |sock| {
        if let Err(e) = sock.set_nodelay(true) {
            return Err(e);
        }

        let serve = server.serve_with(sock, http.clone());
        tokio::spawn(serve.map_err(|e| error!("hyper error: {:?}", e)));

        Ok(())
    })
    .map_err(|e| eprintln!("accept error: {}", e));

tokio::run(serve)

how to modify these code ?
thank you!!!

This looks to be unimplemented at the moment (see: #2) However, it's easy enough to use tokio to ::spawn two services on different ports for the time being.

What @davidvartan suggested works, there are ways you can manually build a router to serve both on the same socket. This would require you to detect the incoming path. Mostly likely need to write some custom services like so https://github.com/tower-rs/tower-hyper/blob/master/examples/server.rs#L41. This is roughly what tower-grpc-build does but you can wrap it. Then dispatch the call based on the incoming path.

ok, I will try it in the next day by using your idea.
