Description

Mutable boxed and unboxed arrays in the IO monad.

Synopsis

Documentation

newtype IOArray i e

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 of Ix)
  • e: the element type of the array.

Constructors

IOArray (STArray RealWorld i e) 

Instances

newtype IOUArray i e Source

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.

Constructors

IOUArray (STUArray RealWorld i e) 

Instances

castIOUArray :: IOUArray ix a -> IO (IOUArray ix 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...).
