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.
