map :: MonadState (Deque a) m => (a -> a) -> m () Source #
O(n). Modify each element of the queue.
cons :: MonadState (Deque a) m => a -> m () Source #
O(1). Add element in the beginning.
snoc :: MonadState (Deque a) m => a -> m () Source #
O(1). Add element in the ending.
reverse :: MonadState (Deque a) m => m () Source #
O(1). Reverse the deque.
shiftLeft :: MonadState (Deque a) m => m () Source #
O(1), occasionally O(n). Move the first element to the end.
shiftRight :: MonadState (Deque a) m => m () Source #
O(1), occasionally O(n). Move the last element to the beginning.
filter :: MonadState (Deque a) m => (a -> Bool) -> m () Source #
O(n). Leave only the elements satisfying the predicate.
take :: MonadState (Deque a) m => Int -> m () Source #
O(n). Leave only the specified amount of first elements.
drop :: MonadState (Deque a) m => Int -> m () Source #
O(n). Drop the specified amount of first elements.
takeWhile :: MonadState (Deque a) m => (a -> Bool) -> m () Source #
O(n). Leave only the first elements satisfying the predicate.
dropWhile :: MonadState (Deque a) m => (a -> Bool) -> m () Source #
O(n). Drop the first elements satisfying the predicate.
uncons :: MonadState (Deque a) m => m (Maybe a) Source #
O(1), occasionally O(n). Get the first element and deque without it if it's not empty.
unsnoc :: MonadState (Deque a) m => m (Maybe a) Source #
O(1), occasionally O(n). Get the last element and deque without it if it's not empty.
head :: MonadState (Deque a) m => m (Maybe a) Source #
O(1), occasionally O(n). Get the first element if deque is not empty.
last :: MonadState (Deque a) m => m (Maybe a) Source #
O(1), occasionally O(n). Get the last element if deque is not empty.
tail :: MonadState (Deque a) m => m () Source #
O(1), occasionally O(n). Keep all elements but the first one.
init :: MonadState (Deque a) m => m () Source #
O(1), occasionally O(n). Keep all elements but the last one.
