Embedded and especially bare-metal applications really are 2nd class citizens in the rust ecosystem though. You basically can't use cargo (or at least not without a whole bunch of hacks) and many important features for low-level code are still gated and won't be available for 1.0.

I think it's a bit of a shame because that's basically the #1 differentiator with languages like Go or Java as far as I'm concerned.

But beyond that it's true that the language itself has a lot of potential for embedded applications. The runtime can be made almost as tiny as C's and with libcore you get a much nicer and safer "bare metal" environment than what you'd get in C. And thanks to LLVM you can easily target a whole bunch of architectures.
