Depends what you mean by "embedded," but almost every set-top box and TV has a 32 bit ARM SOC. These run software under active development: web browsers, Netflix, etc.
Also just to be clear I don't say that rust isn't for embedding, just currently development is focused around server (and kinda desktop) usage with some focus on some
of the most wide spread embedding targets.
I hope in the future rust will be the go-to alternative for C/C++ in any use-case (at least any which llvm supports). But we are not there yet. But we are slowly getting there step by step.
