This simple utility wraps an IORef around random for the common use case of initializing an RNG once and using it in various places within an IO context. The haddocks should otherwise be self explanatory.
Any comments, improvement opportunities, feedback most welcome.
In version 0.3.0, rng-utils switched from targeting
random sees more use in the Haskell ecosystem, has fewer
dependencies and the performance difference was negligible in
comparison to the concurrency mechanism. If you feel strongly that
mwc-random should be part of the library, let us know in an issue
and we can look into supporting multiple backends.
