random-adaptor

Adaptor to switch among random packages easily.

Random package support status

Supported

  • splitmix

Planned

  • tf-random
  • random

Postponed

Because they do not provide pure interfaces, Need to write IO monad wrapper and generalization for pure packages.

  • pcg-random
  • mwc-random
  • sfmt

Limitation

  • Only for pure interface (IO or ST monad interfaces are not supported yet)
  • The dependency footprint is too big because of the character of the package
    • This can be resolved by providing an adaptor package for each random package, but this means that there would be very many packages.

Why do I need adaptor series?

Not only for a unified function interface, but for benchmarking and comparing the performance of each library.

When you write a comparing benchmark, you may not need this. However, when you write a real application, you may want an adaptor which helps easy switching among the packages.

How about Backpack instead of Adaptor series?

Yes, Backpack is a beautiful feature. However, even with Backpack, when the interfaces among the target packages are not the same, we still needs an Adaptor package.
