A simple brpc-rs service

use brpc_sys::proto_gen;

fn main() {
    match proto_gen::compile_protos(&["proto/echo.proto"]) {
        Ok(_) => (),
        Err(e) => println!("{:?}", e),
    }
}

        service.set_echo_handler(&mut move |f, t| {

            Ok(())
        });

        let mut server = Server::new();
        let mut options = ServerOptions::new();
        options.set_idle_timeout_ms(1000);
        server.add_service(&service, 1);
        server.start(50000, &options);
        server.run();
    }
}

What is this?
Some kind of ping server?
