## Crate of the Week

<!-- COTW goes here -->
This week's crate is [tokio-netem](https://crates.io/crates/tokio-netem), a toolbox of Tokio AsyncRead /AsyncWrite adapters to emulate latency, throttling, slicing, termination, forced shutdown, data injection and data corruption.

Thanks to [Viacheslav Biriukov](https://users.rust-lang.org/t/crate-of-the-week/2704/1478) for the self-suggestion!

[Please submit your suggestions and votes for next week][submit_crate]!
