示例

使用 &mut

use borrowed_thread;

let mut owned = "ABC".to_owned();

let borrowed_handle = borrowed_thread::spawn(|| {
    owned.push('D');
    0
});

let ret = borrowed_handle.join().expect("join err");

assert_eq!(0, ret);
assert_eq!("ABCD", owned);

使用 &

use borrowed_thread;

let owned = "ABC".to_owned();

let borrowed_handle = borrowed_thread::spawn(|| {
    assert_eq!("ABC", owned);
    0
});

let ret = borrowed_handle.join().expect("join err");

assert_eq!(0, ret);

当没有 join 时释放会 panic

let mut owned = "ABC".to_owned();

let borrowed_handle = borrowed_thread::spawn(|| {
    owned.push('D');
    0
});

// this will cause panic!
drop(borrowed_handle);

assert_eq!("ABCD", owned);
