Quick Reference
Rust Ownership: Each value has one owner. Value dropped when owner goes out of scope. Move by default, Copy for primitives. Borrowing: &T immutable (many), &mut T mutable (one). Lifetimes ensure refs valid. Use 'a when compiler needs help. Clone for explicit copies. Rc/Arc for shared ownership.
