I am a novice when it comes to rust but as I recall the instant you put anything that isn't a scalar type you need lifetimes. Is that what the person you are r

  Very rarely do you need to pass around a lifetime-bound struct or enum that isn't _also_ meant to be temporary. (One database pool has database connections lifetime bound, for example, but the pool still owns the connection.) When I do, I generally eat the cost and put it behind a Rc/Arc, where cloning is cheap. It is 'borrowing' because you don't own it, not because you don't want to clone/copy it. Sometimes it is cheaper to borrow than it is to clone/copy; sometimes it is not.
