Example Concept: Rust's ownership system 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 deallocated. Borrowing allows references to data without taking ownership, with rules to prevent data races by enforcing either one mutable reference or multiple immutable references at a time. Lifetimes ensure that references are valid as long as they are used, preventing dangling pointers.
