so yes, c things are being ported to rust, but in situations they would have been ported to cpp.
Not quite. I doubt librsvg would have been ported to C++ if Rust didn't exist. Nor do I believe that C++ would have been allowed into the Linux kernel as readily as Rust currently is, e.g. Android's binder.
Sure, Rust is a small language, but it is making consistent progress and it is only becoming more of a viable C replacement. Of course, C isn't going anywhere and the vast majority of C code is not going to be rewritten in Rust. However, that is normal in the lifecycle of programming languages, i.e. codebases are not usually rewritten, they simply become obsolete and are replaced. Just like Java didn't need to replace every line COBOL to become the enterprise language of choice, Rust doesn't need to replace C everywhere to become the preferred systems programming language.
