We must produce an owned value inside the function to return it! The lifetime labels for function parameters and return values. All rust references have an associated lifetime, indicated by a lifetime label (e.g., 'a). You just want a borrow on the object (quite possibly shorter than the entire lifetime of the object), and you want the resulting reference to have the. These annotations are used to connect the lifetimes of various parameters and return values in. These are both common situations, and it’s easy to get.
