Well the argument would be that since Rust is built on LLVM, and actually maps quite closely to the semantics of C, there already is decades worth of production tested compiler infrastructure beneath it.
Of course there still are bugs from the rest of the architecture, but I'd recommend you check out the way the compiler is being built. It is a lot more structured and well organized than most other projects I know of (both open source and commercial), I'd bet we're getting to the point where a new release of Rust has more structured and well thought out decisions made on it then for example C++20 would have, but then I'm crossing into more subjective territory so I won't make any hard statements there.
Well congratulations for sparking my interest in Rust. I understand your LLVM argument in favour of Rust; it has its merits. Also, function arguments in Rust remind me of Pascal which was my first programming language, the one that got me hooked to programming. Who knows, maybe I will finally find a friend for my goold old C buddy 😁. I've done a lot of C++ and it was that final disdain that made me use C exclusively. I'm going to keep my eye on Rust, thanks.
