I was speaking more abstractly. Strictly speaking, a pointer points to 1 address, not a set. Abstractly speaking, a lifetime represents a set of memory that lives a certain length of time, and thus also represents the set of memory a reference with that lifetime can reference. It's just a different way of thinking about lifetimes which helped me understand them. |

Rust "fat pointers" like `&str` contain a length as well.

No, you can have memory that is alive for a particular lifetime but that you are not allowed to access via a pointer with said lifetime (because it's out of bounds).
