Hands-On Microservices with Rust

main function

Now, we can add a main function to spawn an actor with the decoding worker:

fn main() -> Result<(), Error> {    env_logger::init();    let mut sys = System::new("rabbit-actix-worker");    let _ = QueueActor::new(WokerHandler {}, &mut sys)?;    let _ = sys.run();    Ok(())}

This method starts a System and creates an instance of QueueActor with an instance of WorkerHandler. That's all. It's really simple—with QueueActor, it's enough to implement QueueHandler to make a processor to a queue. Let's create a server in a similar way.
