Struct heron::rapier_plugin::rapier::crossbeam::deque::Stealer [−]
pub struct Stealer<T> { /* fields omitted */ }
A stealer handle of a worker queue.
Stealers can be shared among threads.
Task schedulers typically have a single worker queue per worker thread.
Examples
use crossbeam_deque::{Steal, Worker}; let w = Worker::new_lifo(); w.push(1); w.push(2); let s = w.stealer(); assert_eq!(s.steal(), Steal::Success(1)); assert_eq!(s.steal(), Steal::Success(2)); assert_eq!(s.steal(), Steal::Empty);
Implementations
impl<T> Stealer<T>
pub fn is_empty(&self) -> bool
Returns true
if the queue is empty.
use crossbeam_deque::Worker; let w = Worker::new_lifo(); let s = w.stealer(); assert!(s.is_empty()); w.push(1); assert!(!s.is_empty());
pub fn steal(&self) -> Steal<T>
Steals a task from the queue.
Examples
use crossbeam_deque::{Steal, Worker}; let w = Worker::new_lifo(); w.push(1); w.push(2); let s = w.stealer(); assert_eq!(s.steal(), Steal::Success(1)); assert_eq!(s.steal(), Steal::Success(2));
pub fn steal_batch(&self, dest: &Worker<T>) -> Steal<()>
Steals a batch of tasks and pushes them into another worker.
How many tasks exactly will be stolen is not specified. That said, this method will try to steal around half of the tasks in the queue, but also not more than some constant limit.
Examples
use crossbeam_deque::Worker; let w1 = Worker::new_fifo(); w1.push(1); w1.push(2); w1.push(3); w1.push(4); let s = w1.stealer(); let w2 = Worker::new_fifo(); let _ = s.steal_batch(&w2); assert_eq!(w2.pop(), Some(1)); assert_eq!(w2.pop(), Some(2));
pub fn steal_batch_and_pop(&self, dest: &Worker<T>) -> Steal<T>
Steals a batch of tasks, pushes them into another worker, and pops a task from that worker.
How many tasks exactly will be stolen is not specified. That said, this method will try to steal around half of the tasks in the queue, but also not more than some constant limit.
Examples
use crossbeam_deque::{Steal, Worker}; let w1 = Worker::new_fifo(); w1.push(1); w1.push(2); w1.push(3); w1.push(4); let s = w1.stealer(); let w2 = Worker::new_fifo(); assert_eq!(s.steal_batch_and_pop(&w2), Steal::Success(1)); assert_eq!(w2.pop(), Some(2));
