JavaScriptView Source Request Example

function WaitAsync(key, cancellationToken);

Parameters

key TKey: Key to wait on.
cancellationToken CancellationToken (Optional): Optional token to cancel or timeout the wait.

Return Value

TaskTResult
A task that completes when signaled, failed, or canceled.

Remarks

We never remove the per-key bucket on cancellation—only individual waiters. Buckets are removed on Signal(TKey, TResult)/Fail(TKey, Exception) or by periodic pruning. A mapping-stability check ensures we never add to an orphaned bucket.

Exceptions

ObjectDisposedException

Thrown if the instance has been disposed.
