In Zig, dividing by 0 does not panic unless you decide that it should or go out of your way to use unsafe primitives [1]. Same for trying to allocate more memory than is available. The general difference is as follows (IMO):
Rust tries to prevent developers from doing bad things, then has to include ways to avoid these checks for cases where it cannot prove that bad things are actually OK. Zig (and many others such as Odin, Jai, etc.) allow anything by default, but surface the fact that issues can occur in its API design. In practice the result is the same, but Rust needs to be much more complex both to do the proving and to allow the developers to ignore its rules.
