Attempts to enqueue the given element at the back of the queue without semantically blocking.
Attempts to enqueue the given element at the back of the queue without semantically blocking.
Value parameters
- a
-
the element to be put at the back of the queue
Attributes
- Returns
-
an effect that describes whether the enqueuing of the given element succeeded without blocking
- Inherited from:
- QueueSink
- Source
- QueueSink.scala
Attempts to enqueue the given elements without semantically blocking.
Attempts to enqueue the given elements without semantically blocking. If an item in the list cannot be enqueued, the remaining elements will be returned. This is a convenience method that recursively runs tryOffer
and does not offer any additional performance benefits.
Value parameters
- list
-
the elements to be put in the PQueue
Attributes
- Returns
-
an effect that contains the remaining valus that could not be offered.

Attempts to dequeue an element from the front of the queue, if one is available without fiber blocking.
Attempts to dequeue an element from the front of the queue, if one is available without fiber blocking.
Attributes
- Returns
-
an effect that describes whether the dequeueing of an element from the queue succeeded without blocking, with
None
denoting that no element was available - Inherited from:

- Source
- QueueSource.scala
Attempts to dequeue elements from the PQueue, if they are available without semantically blocking.
Attempts to dequeue elements from the PQueue, if they are available without semantically blocking. This is a convenience method that recursively runs tryTake
. It does not provide any additional performance benefits.
Value parameters
- maxN
-
The max elements to dequeue. Passing
None
will try to dequeue the whole queue.
Attributes
- Returns
-
an effect that contains the dequeued elements from the PQueue Note: If there are multiple elements with least priority, the order in which they are dequeued is undefined.
