Enum cordyceps::mpsc_queue::TryDequeueError

source · [−]

pub enum TryDequeueError {
    Empty,
    Inconsistent,
    Busy,
}

Expand description

Errors returned by MpscQueue::try_dequeue and Consumer::try_dequeue.

Variants

`Empty`

No element was dequeued because the queue was empty.

`Inconsistent`

The queue is currently in an inconsistent state.

Since inconsistent states are very short-lived, the caller may want to try dequeueing a second time.

`Busy`

Another thread is currently calling MpscQueue::try_dequeue or MpscQueue::dequeue, or owns a Consumer or OwnedConsumer handle.

This is a multi-producer, single-consumer queue, so only a single thread may dequeue elements at any given time.
