copy that data into memory multiple times. References are a complex feature, and one of Rust’s major advantages is how safe and easy it is to use references. You don’t need to know a lot of those details details to finish this program: Chapter 4 will explain references more thoroughly. For now, all you need to know is that like variables, refer- ences are immutable by default. Hence, we need to write &mut should be common. Luckily for us, Rust has a feature for this concept, and it’s called references. 4.2 References and Borrowing The issue with the tuple code at the end of the preceding section is that
