Isolation in rust

isolation.rs

// Shared fate: threads in one process
let data = Arc::new(Mutex::new(vec![]));
thread::spawn({
    let data = data.clone();
    move || {
        let mut d = data.lock().unwrap();
        panic!("oops");  // Mutex now poisoned for everyone
    }
});

// Isolated: separate processes
Command::new("./worker")
    .spawn()
    .expect("failed to spawn");
// Worker crashes? Main process is fine. Restart the worker.
