Shame to see this not going anywhere but I can’t shake the feeling that maybe we don’t want too much competition in the low-level memory-safe language space, if everyone agrees Rust is the way to go then we can have more software written in the same language. Maybe naive of me though.
Rust at the kernel level is great. But as for specific microcontrollers and microprocessors, I’m not sure if Rust has an edge over C. Rust should arguably replace C++ moving forward, but not everyone is able to migrate an entire codebase to a fancy new language. C/C++ are still here, and Rust is moving lightning fast (maybe faster than what stability would like). Otherwise Ada is likely the next go to safe language.
We do see it in use for things like trussed the firmware for the Nitrokey 3. I think like anything it’s just about adoption, will probably happen more and more.
