Example Concept: Rust's ownership model ensures that each value in the program has a single owner at any given time. Ownership can be transferred, but when a value goes out of scope, Rust automatically deallocates it. Borrowing allows references to data without taking ownership, with rules that prevent data races: you can have either one mutable reference or any number of immutable references to a piece of data, but not both simultaneously. This compile-time checking prevents data races by ensuring that no two threads can simultaneously modify shared data.
