Struct rayon_core::latch::CountLatch

pub(crate) struct CountLatch {
    counter: AtomicUsize,
    kind: CountLatchKind,
}

Counting latches are used to implement scopes. They track a counter. Unlike other latches, calling set() does not necessarily make the latch be considered set(); instead, it just decrements the counter. The latch is only “set” (in the sense that probe() returns true) once the counter reaches zero.

Fields

counter: AtomicUsize

kind: CountLatchKind
