data MArray s a Source #

Creation

new :: Int -> a -> ST s (MArray s a) Source #

Create a new mutable array of specified size, in the specified state thread, with each element containing the specified initial value.

new_ :: Int -> ST s (MArray s a) Source #

singletonM :: a -> ST s (Array a) Source #

pair :: a -> a -> Array a Source #

Basic interface

read :: MArray s a -> Int -> ST s a Source #

write :: MArray s a -> Int -> a -> ST s () Source #

index :: Array a -> Int -> a Source #

indexM :: Array a -> Int -> ST s a Source #

index# :: Array a -> Int -> (# a #) Source #

update :: Array e -> Int -> e -> Array e Source #

O(n) Update the element at the given position in this array.

updateWith' :: Array e -> Int -> (e -> e) -> Array e Source #

O(n) Update the element at the given positio in this array, by applying a function to it. Evaluates the element to WHNF before inserting it into the array.

unsafeUpdateM :: Array e -> Int -> e -> ST s () Source #

O(1) Update the element at the given position in this array, without copying.

insert :: Array e -> Int -> e -> Array e Source #

O(n) Insert an element at the given position in this array, increasing its size by one.

insertM :: Array e -> Int -> e -> ST s (Array e) Source #

O(n) Insert an element at the given position in this array, increasing its size by one.

delete :: Array e -> Int -> Array e Source #

O(n) Delete an element at the given position in this array, decreasing its size by one.

sameArray1 :: (a -> b -> Bool) -> Array a -> Array b -> Bool Source #

trim :: MArray s a -> Int -> ST s (Array a) Source #

Create a new array of the n first elements of mary.

unsafeThaw :: Array a -> ST s (MArray s a) Source #

run :: (forall s. ST s (MArray s e)) -> Array e Source #

copy :: Array e -> Int -> MArray s e -> Int -> Int -> ST s () Source #

Unsafely copy the elements of an array. Array bounds are not checked.

copyM :: MArray s e -> Int -> MArray s e -> Int -> Int -> ST s () Source #

Unsafely copy the elements of an array. Array bounds are not checked.
