Are there mature versions of rust for the hundreds of microcontrollers that people are in production right now? Most of them have a decent GCC port and C works on all of them..
In general, the versions of Rust end up being most of them, rather than being pinned to one specific version.
As my sibling mentions, if LLVM can target it, then we can, but generally anything < 32 bits isn't gonna work at the moment. We're slowly getting support for some of that stuff.
Rust uses LLVM on the backend, so it gets a lot of platform support for free. Not sure how mature that stuff is yet though. Maybe someone who's used Rust for embedded can jump in and comment?
