def takeFront: F[A]

Dequeues an element from the front of the dequeue, possibly semantically blocking until an element becomes available.

def tryTakeBack: F[Option[A]]

Attempts to dequeue an element from the back of the dequeue, if one is available without fiber blocking.

Attempts to dequeue an element from the back of the dequeue, if one is available without fiber blocking.

Attributes

Returns

an effect that describes whether the dequeueing of an element from the dequeue succeeded without blocking, with None denoting that no element was available

def tryTakeBackN(maxN: Option[Int])(implicit F: Monad[F]): F[List[A]]

Attempts to dequeue elements from the back of the dequeue, if they available without semantically blocking. This is a convenience method that recursively runs tryTakeBack. It does not provide any additional performance benefits.

Attempts to dequeue elements from the back of the dequeue, if they available without semantically blocking. This is a convenience method that recursively runs tryTakeBack. 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

def tryTakeN(maxN: Option[Int])(implicit F: Monad[F]): F[List[A]]

Attempts to dequeue elements from the front of the queue, if they are available without semantically blocking. This method does not guarantee any additional performance benefits beyond simply recursively calling tryTake, though some implementations will provide a more efficient implementation.
