I’ve not looked into Zig yet (just like you must not have looked very closely into rust, since most of the stuff you mention as a Zig highlight is present in Rust too), so I’m not gonna argue which one may be “better” (if I had to bet, I’d say both are great in their own way - OP’s question is IMHO kinda dumb to begin with).

I want, however, to point out a misconception: “unsafe” rust code is not code that is bugged or in any way inferior to “regular” code, it’s just code (usually small pieces) whose safety is checked and guaranteed by the developer rather than the compiler. Yeah, they really should have picked a different name for it… possibly one that isn’t literally the contrary of “safe”.
