Add count, which returns the number of timers in a timer wheel
Add Seconds type alias for readability
Add Timer newtype for readability
Make create / with no longer throw an exception if given an invalid config; rather, the config’s invalid values are
replaced with sensible defaults
Make recurring / recurring_ handle delays that are shorter than the wheel resolution more correctly
Make recurring / recurring_ no longer throw an exception if given a negative delay
Make calling cancel more than once on a recurring timer not enter an infinite loop
Make timers that expire in the same batch no longer fire in an arbitrary order
Improve the resolution of timers from microseconds to nanoseconds
Simplify and optimize internals
[0.4.0.1] - November 5, 2022
Fix inaccurate haddock on recurring
[0.4.0] - November 5, 2022
Add create
Rename Data.TimerWheel to TimerWheel
Swap out vector for array
Treat negative delays as 0
Drop support for GHC < 8.6
[0.3.0] - June 18, 2020
Add with
Add support for GHC 8.8, GHC 8.10
Change type of spokes from Natural to Int
Change order of delay and action arguments in register, register_, recurring, and recurring_
Simplify cancel to return True at most once
Throw an error if a negative delay is provided to register, register_, recurring, or recurring_
Fix underflow bug that affected recurring timers
Remove create, destroy
Remove TimerWheelDied exception. with now simply re-throws the exception that the timer wheel thread throws
Remove InvalidTimerWheelConfig exception. error is used instead
Remove support for GHC < 8.6
[0.2.0.1] - May 19, 2019
Swap out ghc-prim and primitive for vector
[0.2.0] - February 3, 2019
Add destroy function, for reaping the background thread
Add recurring_ function
If the timer wheel reaper thread crashes, it will propagate the exception to
the thread that spawned it
new may now throw InvalidTimerWheelConfig
The cancel action returned by register is now memoized, which fixes a bug
involving trying to cancel a recurring timer twice. The second call used to
spin forever and peg a CPU
