I think you're really intended to do the latter rather than the former. I mean, Rust lets you do either–it gives you the choice if performance isn't your concern–but usually it's better to not clone everything.

Nah, either is fine. Rust gives you the tools to do both for good reason. Which is right for you completely depends.
