Variants

Stealing

A latch for scopes created on a rayon thread which will participate in work- stealing while it waits for completion. This thread is not necessarily part of the same registry as the scope itself!

Fields

latch: CoreLatch

registry: Arc<Registry>

If a worker thread in registry A calls in_place_scope on a ThreadPool with registry B, when a job completes in a thread of registry B, we may need to call notify_worker_latch_is_set() to wake the thread in registry A. That means we need a reference to registry A (since at that point we will only have a reference to registry B), so we stash it here.

worker_index: usize

The index of the worker to wake in registry

Blocking

A latch for scopes created on a non-rayon thread which will block to wait.

Fields

latch: LockLatch
