## Crate of the Week

<!-- COTW goes here -->
This week's crate is [wtransport](https://crates.io/crates/wtransport), an implementation of the WebTransport specification, a successor to WebSockets with many additional features.

Thanks to [Josh Triplett](https://users.rust-lang.org/t/crate-of-the-week/2704/1369) for the suggestion!

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

# Quote of the Week

<!-- QOTW goes here -->
> Any sufficiently complicated C project contains an adhoc, informally specified, bug ridden, slow implementation of half of cargo.

Thanks to [Collin Richards](https://users.rust-lang.org/t/twir-quote-of-the-week/328/1629) for the suggestion!
