Module clock

A configurable source of time.

This module provides an API to get the current instant in such a way that the source of time may be configured. This allows mocking out the source of time in tests.

The now function returns the current Instant. By default, it delegates to Instant::now.

The source of time used by now can be configured by implementing the Now trait and passing an instance to with_default.
