This crates provides tokio-timer-like API on top of timerfd. timerfd is a Linux-specific API providing timer notifications as file descriptor read events.

The advantage of timerfd is that it has more granularity than epoll_wait(), which only provides 1 millisecond timeouts. timerfd API allows for nanosecond precision, but precise timing of the wakeup is not guaranteed on a normal multitasking system.

Despite the name, this crate is not a part of the tokio project.

• Delay: A future that completes at a specified instant in time.
• Interval A stream that yields at fixed time intervals.
• DelayQueue: A queue where items are returned once the requested delay has expired.
