pub struct Worker<T> { /* private fields */ }
Expand description
The worker side of a deque.
Workers push elements into the back and pop elements depending on the strategy:
- In FIFO deques, elements are popped from the front.
- In LIFO deques, elements are popped from the back.
A deque has only one worker. Workers are not intended to be shared among multiple threads.
Implementations§
source§impl<T> Worker<T>
impl<T> Worker<T>
sourcepub fn is_empty(&self) -> bool
pub fn is_empty(&self) -> bool
Returns true
if the deque is empty.
use crossbeam_deque as deque;
let (w, _) = deque::lifo();
assert!(w.is_empty());
w.push(1);
assert!(!w.is_empty());
sourcepub fn push(&self, value: T)
pub fn push(&self, value: T)
Pushes an element into the back of the deque.
Examples
use crossbeam_deque as deque;
let (w, _) = deque::lifo();
w.push(1);
w.push(2);
sourcepub fn pop(&self) -> Pop<T>
pub fn pop(&self) -> Pop<T>
Pops an element from the deque.
Which end of the deque is used depends on the strategy:
- If this is a FIFO deque, an element is popped from the front.
- If this is a LIFO deque, an element is popped from the back.
Examples
use crossbeam_deque::{self as deque, Pop};
let (w, _) = deque::fifo();
w.push(1);
w.push(2);
assert_eq!(w.pop(), Pop::Data(1));
assert_eq!(w.pop(), Pop::Data(2));
assert_eq!(w.pop(), Pop::Empty);
