A BarrierWaitResult

impl BarrierWaitResult
1.0.0 · Sourcepub fn is_leader(&self) -> bool
pub fn is_leader(&self) -> bool
Returns true
if this thread is the “leader thread” for the call to

let barrier = Barrier::new(1);
let barrier_wait_result = barrier.wait();
println!("{:?}", barrier_wait_result.is_leader());
