I'd like to point out, the value add of Rust isn't speed, it's safety in a low-level language. C is also just as fast, it's just that Rust guarantees safety in a wide class of potential catastrophic bugs with little to no runtime overhead, by using the design of the language and compiler.
I wanted to try zig a couple of times now but was always put off by lacking tooling and generally bad compiler errors. Its kinda hard to justify spending time on something if you see the compiler point out an error inside a standart lib zig file and there is no directon for a fix whatsoever. Im hoping it'll get better because the language seems really great
