Trait appliance::Message [−][src]
Message
must be implemented for any type which is intended for
sending to appliances.
Example
type Counter = Appliance<'static, usize>; struct Ping; impl Message for Ping { type Result = usize; } impl Handler<Ping> for Counter { fn handle(&mut self, _msg: &Ping) -> usize { *self.state() += 1; *self.state() } } fn do_ping(descriptor: Descriptor<Counter>) { match descriptor.send_and_wait_with_timeout(Ping, Duration::from_secs(10)) { Ok(cnt) => println!("Appliance was pinged successfully {} times", *cnt), Err(err) => panic!("Ping to appliance has failed: {}", err), } }
