Module timerfd 

A Tokio-based wrapper around the Linux timerfd API.

Compared to a conventional timer like the ones provided by tokio itself, a timerfd is handled by the kernel. Among other things, this means that the timer can keep running even when the system is suspended. When using ClockId::CLOCK_BOOTTIME_ALARM or ClockId::CLOCK_REALTIME_ALARM, the timer can even wake the system from suspend.

Structs

TimeSpec

TimerFd

A timer file descriptor.

TimerSetTimeFlags

Flags that are used for arming the timer.

Wrapper 🔒

This wrapper is needed because AsyncFd requires the inner type to implement AsRawFd.

Enums

ClockId

The type of the clock used to mark the progress of the timer. For more details on each kind of clock, please refer to timerfd_create(2).

Expiration

An enumeration allowing the definition of the expiration time of an alarm, recurring or not.
