Right, in particular objects (in the general sense, not the OOP sense) have lifetimes and so the provenance of a pointer to or into that object is restricted to the lifetime. If I make a Box<Goose> some heap is allocated and my Goose is in there, and I can get myself a pointer to that Goose, but the pointer must not be used either before I made the Box<Goose> or after it's dropped. |
