Struct coco::deque::Worker

pub struct Worker<T> { /* fields omitted */ }

Worker side of a work-stealing deque.

There is only one worker per deque.

Methods

impl<T> Worker<T>

fn len(&self) -> usize

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);

fn push(&self, value: T)

Pushes an element onto the bottom of the deque.

Examples

use coco::deque;

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

fn pop(&self) -> Option<T>

Pops an element from the bottom of the deque.

Examples

use coco::deque;

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

assert_eq!(w.pop(), Some(2));
assert_eq!(w.pop(), Some(1));
assert_eq!(w.pop(), None);

fn steal(&self) -> Option<T>

Steals an element from the top of the deque.

Examples

use coco::deque;

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

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