Example Concept: Rust's ownership model is based on three core principles: ownership, borrowing, and lifetimes. Ownership ensures that each piece of data has one owner, and when the owner goes out of scope, the data is automatically deallocated. Borrowing allows references to data without transferring ownership, while lifetimes ensure that references are valid as long as they are used. This compile-time checking eliminates many common memory errors found in languages with garbage collection.
