Struct Barrier 

pub struct Barrier { /* private fields */ }

A barrier that releases all n participants together once every one of them has called Barrier::wait.

Implementations

impl Barrier

pub const fn new(n: usize) -> Self

Create a barrier requiring n participants per generation. n == 0 behaves like n == 1 (a single wait() call releases immediately as the leader) rather than a barrier no wait() call could ever complete.

pub async fn wait(&self) -> BarrierWaitResult

Wait for every one of this barrier’s n participants to arrive. Exactly one of the n calls in each generation gets back a BarrierWaitResult with is_leader true; the rest get false. All n calls return together.
