You can technically do it, but it's a convoluted path. The article talks about it. Basically to bootstrap that way you need to go through a lot of versions of rust, compile rust 0.7 in ocaml, compile ocaml in scheme, and compile scheme in C using gcc. For gcc you need to compile a chain of versions back to when it was written in C instead of C++, plus the whole TinyCC bootstrapping path.

edit: had listed scala instead of ocaml

compile rust 0.7 in scala

Not sure if there was another rewrite, but AFAIK (and the article agrees with me) rustc was originally written in Ocaml

Yeah, I wrote the wrong language. I tend to lump those together in my head as 'big multi-paradigm languages I haven't bothered to learn yet.'
