Understanding Rust Ownership, Borrowing, and Lifetimes
Understanding Rust’s three core memory-management concepts — ownership, borrowing, and lifetimes — from the perspective of memory safety. Ownership guarantees each value has exactly one owner to avoid data races; borrowing lets you access a value without taking ownership, split into mutable and immutable borrows; lifetimes help avoid dangling references and guarantee reference validity. Through side-by-side C++ and Rust code, the article shows how the compiler enforces these rules to keep memory safe.
