Struct heron::rapier_plugin::rapier::crossbeam::sync::WaitGroup [−]
Enables threads to synchronize the beginning or end of some computation.
Wait groups vs barriers
WaitGroup
is very similar to Barrier
, but there are a few differences:
-
Barrier
needs to know the number of threads at construction, whileWaitGroup
is cloned to register more threads. -
A
Barrier
can be reused even after all threads have synchronized, while aWaitGroup
synchronizes threads only once. -
All threads wait for others to reach the
Barrier
. WithWaitGroup
, each thread can choose to either wait for other threads or to continue without blocking.
Examples
use crossbeam_utils::sync::WaitGroup; use std::thread; // Create a new wait group. let wg = WaitGroup::new(); for _ in 0..4 { // Create another reference to the wait group. let wg = wg.clone(); thread::spawn(move || { // Do some work. // Drop the reference to the wait group. drop(wg); }); } // Block until all threads have finished their work. wg.wait();
Implementations
impl WaitGroup
pub fn new() -> WaitGroup
Creates a new wait group and returns the single reference to it.
Examples
use crossbeam_utils::sync::WaitGroup; let wg = WaitGroup::new();
pub fn wait(self)
Drops this reference and waits until all other references are dropped.
Examples
use crossbeam_utils::sync::WaitGroup; use std::thread; let wg = WaitGroup::new(); thread::spawn({ let wg = wg.clone(); move || { // Block until both threads have reached `wait()`. wg.wait(); } }); // Block until both threads have reached `wait()`. wg.wait();
