Rustで安全にthread loopを止める方法

Rustの無限ループで安全にloop処理から抜ける方法は
どの様に書けば良いですか。

use std::{thread, time};

pub struct Worker { }

trait WorkerTrait {
    fn run(&self);
    fn stop(&self);
}

impl Worker {
    fn run(&self) {
        thread::spawn(move || loop {
            println!("worker1 working ");
            thread::sleep(time::Duration::from_millis(1000)); // 擬似処理.
            // thread break?
        });
    }
    fn stop(&self) {
        // to break thread.
    }
}
fn main() {
    let w = Worker {};

    w.run();

    thread::sleep(time::Duration::from_secs(10));

    // stop thread.
    w.stop();
}
