Concrete methods

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.

Value parameters
