There's a lot of weird debate about whether Rust in the kernel is useful or not... in my experience, it's way more useful than I could've ever imagined!
I went from 1st render to a stable desktop that can run run games, browsers, etc. in about two days of work on my driver (!!!)
All the concurrency bugs just vanish with Rust! Memory gets freed when it needs to be freed! Once you learn to make Rust work with you, I feel like it guides you into writing correct code, even beyond the language's safety promises. It's seriously magic!
There is absolutely no way I wouldn't have run into race conditions, UAFs, memory leaks, and all kinds of badness if I'd been writing this in C.
In Rust? Just some logic bugs and some core memory management issues. Once those were fixed, the rest of the driver just worked!!
