Why not? Zig's std library is specifically designed to be usable for freestanding/baremetal targets (e.g. firmware), and the compiler is smart enough to only include the parts of a library (including std) that are actually used. If you do need to reimplement a part of std, you can just... reimplement that part, and import your own implementation instead of the one from std.
Unless you're talking purely about Rust?
I am talking purely about Rust, yes. Firmware tends to use libcore, and if it does happen to dynamically allocate memory, liballoc. libstd assumes you have an OS, so...
