1. applyRandomGenM :: RandomGenM g r m => (r -> (a, r)) -> g -> m a

   random	System.Random.Stateful

   No documentation available.

2. createSystemRandom :: IO GenIO

   mwc-random	System.Random.MWC

   Seed a PRNG with data from the system's fast source of pseudo-random numbers.

3. withSystemRandom :: PrimBase m => (Gen (PrimState m) -> m a) -> IO a

   mwc-random	System.Random.MWC

   Deprecated: Use withSystemRandomST or createSystemSeed or createSystemRandom instead

4. withSystemRandomST :: (forall s . () => Gen s -> ST s a) -> IO a

   mwc-random	System.Random.MWC

   Seed PRNG with data from the system's fast source of pseudo-random numbers and execute computation in ST monad.

5. createSystemRandom :: IO GenIO

   mwc-probability	System.Random.MWC.Probability

   Seed a PRNG with data from the system's fast source of pseudo-random numbers.

6. withSystemRandom :: PrimBase m => (Gen (PrimState m) -> m a) -> IO a

   mwc-probability	System.Random.MWC.Probability

   Seed a PRNG with data from the system's fast source of pseudo-random numbers, then run the given action. This function is unsafe and for example allows STRefs or any other mutable data structure to escape scope:

   >>> ref <- withSystemRandom $ \_ -> newSTRef 1
   
   >>> withSystemRandom $ \_ -> modifySTRef ref succ >> readSTRef ref
   2
   
   >>> withSystemRandom $ \_ -> modifySTRef ref succ >> readSTRef ref
   3
   

7. withSystemRandomST :: (forall s . () => Gen s -> ST s a) -> IO a

   mwc-probability	System.Random.MWC.Probability

   Seed PRNG with data from the system's fast source of pseudo-random numbers and execute computation in ST monad.

8. replicateRandom :: RandomGen g => Int -> g -> (g -> (a, g)) -> ([a], g)

   aws-xray-client	System.Random.XRayCustom

   Runs the supplied function a specified number of times, each time using the new RandomGen value.

9. withRandomGenIORef :: RandomGen g => IORef g -> (g -> (a, g)) -> IO a

   aws-xray-client	System.Random.XRayCustom

   Like getStdRandom, except use a given 'IORef StdGen' instead of the global theStdGen.

10. createSystemRandom :: IO GenIO

    pcg-random	System.Random.PCG

    Seed a PRNG with data from the system's fast source of pseudo-random numbers. All the caveats of withSystemRandom apply here as well.
