If Rust solves the kinds of problems you have, then by all means use it. I don't think there exists a language that's in all aspects better than any other. For me personally, C is the language that gets in my way the least without forcing me to write ASM, and that happens to be highest on my list. If there was a language with the same idea of minimalism behind it as C, but with all the quirks and bad syntax choices out, i'd switch in a heartbeat.
