Synopsis
A timer wheel
Description

This library provides a timer wheel data structure for

  • O(1) registering IO actions to fire after a given amount of time

  • O(1) canceling registered actions

It is similar to TimerManager from 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. However, until 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.
