The concept of smart pointers isn’t unique to Rust: smart pointers originated in C++ and exist in other languages as well.

This pointer enables you to allow data to have multiple owners by keeping track of the number of owners and, when no owners remain, cleaning up the data. @@ -21,7 +21,7 @@ Rust, with its concept of ownership and borrowing, has an additional difference between references and smart pointers: while references only borrow data, in many cases, smart pointers *own* the data they point to. -Though we didn't call them as such at the time, we’ve already encountered a few +Though we didn’t call them as such at the time, we’ve already encountered a few smart pointers in this book, including `String` and `Vec<T>` in Chapter 8. Both these types count as smart pointers because they own some memory and allow you to manipulate it.

Unlike an ordinary struct, smart pointers implement the `Deref` and `Drop` traits. The `Deref` trait allows an instance of the smart pointer struct to behave like a reference so you can write your code to work with either references or smart pointers. -The `Drop` trait allows you to customize the code that's run when an instance +The `Drop` trait allows you to customize the code that’s run when an instance of the smart pointer goes out of scope. In this chapter, we’ll discuss both traits and demonstrate why they’re important to smart pointers. |
