Struct StealerCopy item path

Returns the number of elements in the deque.

If used concurrently with other operations, the returned number is just an estimate.

§Examples

use coco::deque;

let (w, _) = deque::new();
for i in 0..30 {
    w.push(i);
}
assert_eq!(w.len(), 30);

Steals an element from the top of the deque.

§Examples

use coco::deque;

let (w, s) = deque::new();
w.push(1);
w.push(2);

assert_eq!(s.steal(), Some(1));
assert_eq!(s.steal(), Some(2));
assert_eq!(s.steal(), None);

Steals an element from the top of the deque, but may sometimes spuriously fail.

If another concurrent operation gets in the way when stealing data, this method will return immediately with Steal::Inconsistent instead of retrying.

§Examples

use coco::deque::{self, Steal};

let (w, s) = deque::new();
w.push(1);
assert_eq!(s.steal_weak(), Steal::Data(1));

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.
