The library adds roughly 39k lines and is one of the most downloaded Rust crates, also used by the Rust compiler itself. Additionally, Linux 7.2 Rust changes include AutoFDO (Automatic Feedback Directed Optimizations) support — showing ~13% performance improvement in Rust Binder — software tag-based KASAN support, and compatibility with the upcoming Rust 1.98 release. ## Full article daily.dev links to this article rather than hosting it.
