Struct Barrier 

pub struct Barrier(/* private fields */);

A barrier enables multiple threads to synchronize the beginning of some computation.

Implementations

impl Barrier

pub fn new(n: usize) -> Self

Creates a new barrier that can block a given number of threads.

A barrier will block n-1 threads which call Self::wait and then wake up all threads at once when the nth thread calls Self::wait.

pub async fn wait(&self) -> BarrierWaitResult

Blocks the current thread until all threads have rendezvoused here.

Barriers are re-usable after all threads have rendezvoused once, and can be used continuously.
