Rust is an entirely adequate systems language for most purposes. I think it could probably replace C for almost all purposes except in cases where extreme portability is required, which C excels at. C++ is really only the answer if you need extreme performance and/or expressiveness out of a systems language. Some code, like database engines, really benefits from that.
