# Rust Ownership

> - Rust ownership, borrowing, lifetimes, and smart pointers — the mental model plus concrete fixes for borrow-checker errors. Use when fighting the borrow checker, deciding between T / &T / &mut T, choosing Box/Rc/RefCell/Cow, returning references, writing an RAII/scope guard, or lazily initializing a value. Triggers: borrow checker, cannot borrow, does not live long enough, Rc, RefCell, Cow, RAII, OnceLock, E0382, E0499, E0515, E0597, E0716.
