You need to learn both. Both borrow checker (Rust) and comptime (Zig) are huge ideas worth getting your hands dirty with.

If you don't have time to learn both, then learn Zig, as it requires much smaller time investment (though do try to find time for both).

For what it’s worth there’s a comptime crate for Rust. Not as elegant as a language level feature but probably accomplishes very much similar things.

There are plans to experiment with language level comptime support too: https://github.com/rust-lang/rust/pull/148820
