Concurrency and Threads

Rust makes concurrency safe using threads and channels.

Spawning a Thread

use std::thread;

let handle = thread::spawn(|| {
    for i in 1..5 {
        println!("hi from the spawned thread: {}", i);
    }
});

handle.join().unwrap();

Channels

use std::sync::mpsc;

let (tx, rx) = mpsc::channel();
tx.send(String::from("Hello"))?;
println!("Received: {}", rx.recv()?);

Use Arc and Mutex for shared mutable state across threads.
