This address refers to, or "points at" some other data. The most common kind of pointer in Rust is a *reference*, which you learned about in Chapter 4. References are indicated by the `&` symbol and borrow the value they point to. They don't have any special capabilities other than referring to data. Also, they don`t have any overhead and are the kind of pointer used most often.
