There’s a long thread on Mastodon by the main Arm Mac Graphics dev for Asahi Linux. Perhaps one of the fastest developed and most stable graphics drivers ever made, thanks to a couple amazing developers but also very very much thanks to Rust. And one of the kernel devs flippantly calls it an “unmerged toy project” as if it’s not kernel devs’ fault that useful stuff and even small non-breaking improvements to existing systems are so incredibly hard to get merged. Not to mention that writing the entire m1 graphics driver in Rust ended up actually thoroughly documenting the DRM subsystem’s API for the first time as a side effect because everything the Rust code interacts with pretty much gets strictly defined within Rust’s type systems and lifetimes.
