The story for rust in embedded contexts is not quite finished. There are dozens of people writing kernels in rust, there's zinc for arm microcontrollers and I've seen projects for raspi and PSX, so stuff works. It's not great yet, though. Once the allocator api is added to the stdlib it'll be much easier to use the standard library in embedded contexts. There's probably other stuff I don't know about but I know for sure that this is a priority for the near future.
