I’d probably say it depends but I’m no Rust expert and I have no direct experience with C (though quite familiar with C++).

Basically I’d expect writing C to be easy, but not safe. IE you can quickly and easily write C that compiles but has runtime issues. Rust for the most part will catch everything but logic issues during/before compilation meaning once the program runs you’ll have very high confidence in it’s runtime behavior leading to time spent “fighting the compiler” instead of figuring out wtf is going wrong at runtime.
