Module time 

Deterministic time: virtual time under simulation, real time in production.

Under simulation (simulation + cfg(madsim)), Instant is std::time::Instant (madsim intercepts the system clock calls). sleep, timeout, interval advance in virtual time controlled by the deterministic scheduler.

Modules

error

Time error types.

Structs

Duration

A Duration type to represent a span of time, typically used for system timeouts.

Instant

A measurement of a monotonically nondecreasing clock. Opaque and useful only with Duration.

Interval

Interval returned by interval and interval_at.

Sleep

Future returned by sleep and sleep_until.

Enums

MissedTickBehavior

Defines the behavior of an Interval when it misses a tick.

Functions

interval

Creates new Interval that yields with interval of period. The first tick completes immediately. The default MissedTickBehavior is Burst, but this can be configured by calling set_missed_tick_behavior.

interval_at

Creates new Interval that yields with interval of period with the first tick completing at start. The default MissedTickBehavior is Burst, but this can be configured by calling set_missed_tick_behavior.

sleep

Waits until duration has elapsed.

sleep_until

Waits until deadline is reached.

timeout

Requires a Future to complete before the specified duration has elapsed.
