Creation

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

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

Basic interface

length :: Array a -> Int 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.
