catMaybes :: forall a. Array (Maybe a) -> Array a

Filter an array of optional values, keeping only the elements which contain a value, creating a new array.

catMaybes [Nothing, Just 2, Nothing, Just 4] = [2, 4]

untilJust :: forall a m. MonadRec m => m (Maybe a) -> m a

Supplied computation will be executed repeatedly until it evaluates to Just value and then that value will be returned.

whileJust :: forall a m. Monoid a => MonadRec m => m (Maybe a) -> m a

While supplied computation evaluates to Just _, it will be executed repeatedly and results will be combined using monoid instance.

init :: forall a. Partial => Array a -> Array a

Get all but the last element of a non-empty array.

Running time: O(n), where n is the length of the array.

nub :: forall a. Ord a => Array a -> Array a

Remove the duplicates from an array, creating a new array.

nub [1, 2, 1, 3, 3] = [1, 2, 3]

nubEq :: forall a. Eq a => Array a -> Array a

Remove the duplicates from an array, creating a new array.

This less efficient version of nub only requires an Eq instance.

nubEq [1, 2, 1, 3, 3] = [1, 2, 3]

reverse :: forall a. Array a -> Array a

Reverse an array, creating a new array.

reverse [] = []
reverse [1, 2, 3] = [3, 2, 1]

sort :: forall a. Ord a => Array a -> Array a

Sort the elements of an array in increasing order, creating a new array. Sorting is stable: the order of equal elements is preserved.

sort [2, -3, 1] = [-3, 1, 2]

tail :: forall a. Partial => Array a -> Array a

Get all but the first element of a non-empty array.

Running time: O(n), where n is the length of the array.

filtered :: forall m a. MonadRec m => MonadGen m => m (Maybe a) -> m a

compact :: forall f a. Compactable f => f (Maybe a) -> f a

compactDefault :: forall f a. Functor f => Compactable f => f (Maybe a) -> f a

race :: forall f m a. Parallel f m => Alternative f => Array (m a) -> m a

Run multiple computations in parallel, and return the fastest To collect all results, use inParallel instead

nubHash :: forall a. Hashable a => Array a -> Array a

Remove duplicates from an array.

Like nub from Data.Array, but uses a Hashable constraint instead of an Ord constraint.

untilJust :: forall m a. Monad m => m (Maybe a) -> m a

Run the supplied Maybe computation repeatedly until it returns a value. Returns that value.

untilJust :: forall m a. MonadRec m => m (Maybe a) -> m a

Run the supplied "Maybe" computation repeatedly until it returns a value. Returns that value.
