@hackage perfect-vector-shuffle0.1.0

This package contains functions for performing shuffles on mutable and immutable vectors. The shuffles are uniform at random amongst all permuations.

For an example of how to use it:

module Example where

import Data.Vector
import Immutable.Shuffle

myVector :: Vector Int
myVector = fromList [1..10]

shuffleMyVector :: IO (Vector Int)
shuffleMyVector = shuffleM myVector

This gives the following:

> shuffleMyVector
[1,10,4,7,2,3,5,9,8,6]
> shuffleMyVector
[7,4,2,10,9,8,6,5,1,3]
