Module clock 

Time sources for rate limiters.

Custom time sources implement Reference, Clock, and Add<Nanos>. This supports deterministic tests without coupling rate-limiting decisions to wall-clock time.

Structs

FakeRelativeClock

A mock implementation of a clock. All it does is keep track of what “now” is (relative to some point meaningful to the program), and returns that.

MonotonicClock

The monotonic clock implemented by Instant.

Traits

Clock

A time source used by rate limiters.

Reference

A measurement from a clock.
