Description
Mutable boxed and unboxed arrays in the IO monad.
IO arrays with boxed elements
data IOArray i e :: * -> * -> * Source
An IOArray is a mutable, boxed, non-strict array in the IO monad. The type arguments are as follows:
-
i: the index type of the array (should be an instance ofIx) -
e: the element type of the array.
IO arrays with unboxed elements
Mutable, unboxed, strict arrays in the IO monad. The type arguments are as follows:
-
i: the index type of the array (should be an instance ofIx) -
e: the element type of the array. Only certain element types are supported: see Data.Array.MArray for a list of instances.
