Data.Array.IO
Contents
Description
Mutable boxed and unboxed arrays in the IO monad.
IO arrays with boxed elements
data IOArray i e
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.
Instances
castIOUArray :: IOUArray i a -> IO (IOUArray i b)Source
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...).
