Variants

Data(PeekedData<T>)

Some data has been successfully peeked

Empty

The queue is empty

Inconsistent

The queue is in an inconsistent state. Peeking data should succeed, but some pushers have yet to make enough progress in order allow a peek to succeed. It is recommended that a peek() occur “in the near future” in order to see if the sender has made progress or not.
