Unreleased

Added

Changed

  • Docs: Add sanity check to half_period_counter code example
  • Deprecate Monotonic::should_dequeue_check as it was erroneous

Fixed

  • Fix race condition in half_period_counter::calculate_now. This sadly required a minor API change.

v1.1.0 - 2023-12-04

Added

  • half_period_counter containing utilities for implementing a half-period-counter based monotonic.
  • should_dequeue_check to the Monotonic trait to handle bugged timers.

Changed

Fixed

  • Soundness fix: TimerQueue did not wait long enough in Duration based delays. Fixing this sadly required adding a const TICK_PERIOD to the Monotonic trait, which requires updating all existing implementations.
  • If the queue was non-empty and a new instant was added that was earlier than head, then the queue would no pend the monotonic handler. This would cause the new head to be dequeued at the wrong time.

v1.0.0 - 2023-05-31
