Read Control.Proxy.Tutorial for an extended proxy tutorial.



Control.Proxy.Core exports everything except runProxy.

This library provides two base proxy implementations, each of which export their own runProxy function:

  • Control.Proxy.Core.Fast: This runs faster for code that is not IO-bound, but it only obeys the monad transformer laws modulo safe observation functions.
  • Control.Proxy.Core.Correct: This trades speed on pure code segments, but strictly preserves the monad transformer laws.

This module selects the currently recommended implementation (Fast).

You can switch to the correct implementation by importing Control.Proxy.Core and Control.Proxy.Core.Correct.

You can lock in the fast implementation (in case I change the recommended default) by importing Control.Proxy.Core and Control.Proxy.Core.Fast.
