Lib.rs

A drop-in replacement of tokio::time::timeout which is much more efficient.

Similar to tokio::time::timeout but more efficient on busy concurrent IOs where timeouts are created and canceled very frequently.

This crate provides the following optimizations

• The timeouts lazily initializes their timer when the Future is pending for the first time.
• There is no global lock for creating and cancelling timeouts.
• Timeout timers are rounded to the next 10ms tick and timers are shared across all timeouts with the same deadline.
