Hands-On Microservices with Rust

Starting a server

Consider the following code:

fn main() {    env_logger::init();    let sys = actix::System::new("router");    server::new(|| {      // Insert `App` declaration here    }).workers(1)        .bind("127.0.0.1:8080")        .unwrap()        .start();    let _ = sys.run();}

We create a new server with the server::new method call that expects a closure to return the App instance. Before we create the App instance, we have to finish our server and run it. The workers method sets the number of threads to run actors.

You can choose not to set this value explicitly, and by default, it will be equal to the number of CPUs on the system. In many cases, it's the best possible value for performance.

The next call of the bind method binds the server's socket to an address. If ...
