Module timer

Lightweight timer for systems with high rate of operations with timeout associated with them

Users don’t need to interact with this module.

The idea is to bucket timers into finite time slots so that operations that start and end quickly don’t have to create their own timers all the time

Benchmark:

• create 7.809622ms total, 78ns avg per iteration
• drop: 1.348552ms total, 13ns avg per iteration

tokio timer:

• create 34.317439ms total, 343ns avg per iteration
• drop: 10.694154ms total, 106ns avg per iteration

Structs

• TimerManager
