I remember reading one of the earlier Asahi Linux blog posts on HN a while ago: https://asahilinux.org/2022/11/tales-of-the-m1-gpu/

Mind you, I'm a PHP developer by day, so this Rust-vs-C debate and memory management stuff is not something I've had experience with personally, but the "Rust is magical" section towards the bottom seems like a good summary of why the developer chose to use Rust.
