IOUArray +array

data IOUArray i e
array Data.Array.IO, array Data.Array.IO.Safe
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 of Ix) * e: the element type of the array. Only certain element types are supported: see Data.Array.MArray for a list of instances.
castIOUArray :: IOUArray i a -> IO (IOUArray i b)
array Data.Array.IO
Casts an IOUArray with one element type into one with a different element type. All the elements of the resulting array are undefined (unless you know what you're doing...).
castIOUArray :: IOUArray ix a -> IO (IOUArray ix b)
array Data.Array.Unsafe
Casts an IOUArray with one element type into one with a different element type. All the elements of the resulting array are undefined (unless you know what you're doing...).
