## Crate of the Week

<!-- COTW goes here -->
This week's crate is [struct-split](https://github.com/wdanilo/struct-split), a proc macro to implement partial borrows.

Thanks to [Felix](https://users.rust-lang.org/t/crate-of-the-week/2704/1374) for the suggestion!

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

# Quote of the Week

<!-- QOTW goes here -->
> Netstack3 encompasses 63 crates and 60 developer-years of code. It contains more code than the top ten crates on [crates.io](https://crates.io/) combined. ... For the past eleven months, they have been running the new networking stack on 60 devices, full time. In that time, Liebow-Feeser said, most code would have been expected to show "mountains of bugs". Netstack3 had only three; he attributed that low number to the team's approach of encoding as many important invariants in the type system as possible.

– [Joshua Liebow-Feeser at RustConf, as reported by Daroc Alden on Linux Weekly News](https://lwn.net/SubscriberLink/995814/17e451bcb3015920/)
