Zig’s comptime feature is most famous for what it can do: generics!, conditional compilation!, subtyping!, serialization!, ORM! That’s fascinating, but, to be fair, there’s a bunch of languages with quite powerful compile time evaluation capabilities that can do equivalent things. What I find more interesting is that Zig comptime is actually quite restrictive, by design, and won’t do many things! It manages to be very expressive despite being pretty limited. Let’s see! No Host Leakage When you execute code at compile time, on which machine does it execute? The natural answer is “on your machine”, but it is wrong! The code might not run on your machine, it can be cross compiled! For overall development sanity, it is important that comptime code observes the same behavior as the runtime code, and doesn’t leak details about the host on which the code is compiled. ...
