Cell and Mutex for Shared State

Cell<T>: Interior mutability for Copy types via value copying.
Mutex<T>: Thread-safe interior mutability via mutual exclusion locks.

use std::sync::Mutex;

fn main() {
    let m = Mutex::new(0);
    {
        let mut guard = m.lock().unwrap();
        *guard += 1;
    }
    println!("Mutex protected value: {:?}", m.lock().unwrap());
}
