What is tokio-timer?

This crate provides timer facilities for usage with Tokio. Currently, the only timer implementation is a hashed timing wheel, but will provide a binary heap based timer at some point.

A timer provides the ability to set a timeout, represented as a future. When the timeout is reached, the future completes. This can be implemented very efficiently and avoiding runtime allocations.

Hashed Timing Wheel

Inspired by the paper by Varghese and Lauck, the hashed timing wheel is a great choice for the usage pattern commonly found when writing network applications.
