ClockDriver

Struct ClockDriver 

Source
pub struct ClockDriver { /* private fields */ }
Expand description

Drives timer advancement for the clock.

The ClockDriver is responsible for advancing and firing timers associated with the clock. The runtime must call ClockDriver::advance_timers periodically to ensure timers fire at the correct time.

In thread-per-core architectures, each thread owns its own ClockDriver that advances only the timers registered on that thread’s Clock. See the runtime module for the setup pattern.

Implementations§

Source§

impl ClockDriver

Source

pub fn advance_timers( &mut self, now: Instant, ) -> Result<Option<Instant>, ClockGone>

Advances and fires all timers scheduled to execute by the given time.

This method processes all timers scheduled to fire at or before the specified now time, waking their associated tasks.

§Errors

Returns Err(ClockGone) if the all clocks are gone, all timers are fired and advancing the clock is no longer necessary.
