Add "Optimizing Build Performance" section to the Cargo book by Kobzol · Pull Request #15924 · rust-lang/cargo

Empowering everyone to build reliable and efficient software.

The end of the year is a time for reflection, so I thought that I should take a look back at the previous year. And since my main job is currently contributing to open-source, what better way to do that than enumerating all the Rust pull requests that I opened in 2025. In this post, I’ll share stats about my Rust contributions from the past year and also some thoughts about open-source (Rust) maintenance, as this topic is highly relevant right now.
