How to got the address of the client which the RPC being serviced?

[songsenand]

In fact, I need to implement a whitelist function. I tried to found a function which can get the client's address in the source code but could not find it.
So... is there a function that can get the client's address when the client connects?
Thanks for your time!

If we look at the Greeter server example, we can adjust the Greet type to hold a SocketAddr. Then, you can construct a Greet only once a connection is received, and grab the peer address.

let serve = bind
    .incoming()
    .for_each(move |sock| {
        // set_nodelay, etc
        // ...

        match sock.peer_addr() {
            Ok(addr) => {
                let greet = Greet(addr);
                let server = Server::new(server::GreeterServer::new(greet));
                // etc...
            },
            Err(_) => {
                // socket already disconnected, so just skip
                Ok(())
            }
        }
    });
}
