Control.Monad.Par.RNG

This module defines another Par-related class to capture the random number generation capability.

The rand operation provides deterministic parallel random number generation from within a Par monad.

Most likely one will simply use the ParRand the instance provided in this file, which is based on a state transformer carrying the random generator.

Synopsis

classclass ParRand (p :: Type -> Type) where

A ParRand monad is a Par monad with support for random number generation..

(ParFuture fut p, RandomGen g) => ParRand (StateT g p)Defined in monad-par-extras-0.3.3 · Control.Monad.Par.RNG
The most straightforward way to get a ParRand monad: carry a RNG in a state transformer.
