Description

A fake IO monad for testing.

Synopsis

MockIO

A state monad over MockWorld.

Retrieve the current MockWorld.

Replace the current MockWorld.

Mutate the current MockWorld strictly.

Bump the timer by a given number of microseconds.

MockWorld

Just enough state to mock out a basic filesystem and HTTP server.
