# Ownership

There is a new edition of the book and this is an old link.

> Ownership is Rust’s most unique feature, and it enables Rust to make memory safety guarantees without needing a garbage collector.

> 1. Each value in Rust has a variable that’s called its owner.
> 2. There can only be one owner at a time.
> 3. When the owner goes out of scope, the value will be dropped.

Here are the relevant sections in the new and old books:

- in the current edition: Ch 4.00 — Understanding Ownership
- In the first edition: Ch 3.8 — Ownership
