'Embedded' doesn't require supporting everyone's favorite microcontroller. Even if ESP32 is really popular, there's plenty of others. OBTW experimental xtensa backend is landing in upstream llvm lately.
That were just the examples when Rust is not really suitable as a drop-in replacement for C/C++. Of course, if your platform is well-supported by Rust compiler and you don't have to write safety critical applications, then using Rust is just a matter of choice.
I don't argue whether it's good or bad language. It's a quite interesting one with its own pros and cons. If it fits you, then it's great, but you should know its limitations.
