Well, only if Clone/Copy is compatible with the semantics of the API. I.e., the called function doesn't need to modify anything. No &mut params (or data members) except perhaps `&mut self` (which would refer to definitions the same file).
That's usually the case for Rust programs because the language encourages it. Are Zig programs like that?
To be fair, you can throw an Arc<Mutex<_>> or Rc<RefCell<_>> at it if you're starting from something that has multiple "mutable borrows", but that adds runtime cost and complexity.
