This library provides a timer wheel data structure for
IOactions to fire after a given amount of time
O(1) canceling registered actions
It is similar to
GHC.Event, but can scale much better
under concurrent access patterns.
An unreleased version of this library has a
backpack-based signature for
selecting from a variety of different data structures used internally.
backpack has broader support on Hackage, and in Haddocks,
etc, I decided to just hard-code something decent (a priority search queue).
This makes the
O(1) claims above a bit of a lie, as these rely on using a
linked list data structure internally.
