3 questions for c programmers using rust

why rust? not meant to be an antagonistic question. i’ve personally been messing around with both rust and zig on side projects i’d otherwise use c on what has rust actually changed about the way you write systems code? generally, is there anything you approach fundamentally different in rust v c? anywhere you still prefer c to rust? basically, any particular kinds of projects, environments, api, or constraints where c is still the better choice, in your opinion?
