Sampler monad
Sampler type, for running IO computations alongside a random number generator
sampleIO :: Sampler a -> IO a Source #
Takes a Sampler, provides it a random generator, and runs the sampler in the IO context
sampleIOFixed :: Sampler a -> IO a Source #
Takes a Sampler, provides it a fixed generator, and runs the sampler in the IO context
createSampler :: (GenIO -> IO a) -> Sampler a Source #
Takes a distribution which awaits a generator, and returns a Sampler
Sampling functions
Given their distribution parameters, these functions await a generator and
then sample a value from the distribution in the IO monad.
