Example Concept: In Rust, the ownership system consists of three main rules: each value in Rust has a variable that's its owner, there can only be one owner at a time, and when the owner goes out of scope, the value will be dropped. This ensures that memory is automatically cleaned up when it is no longer needed, preventing memory leaks. The borrow checker enforces these rules at compile time, ensuring that references do not outlive the data they point to, further enhancing memory safety.
