What are Rust's ownership rules?

Three: Each value one owner; one owner only; drop on scope exit.

How does Rust manage memory without GC?

Ownership + borrow checker. Compile-time guarantees no leaks or use-after-free.

Does Rust ownership slow down my code?

Nope—zero runtime cost. Faster than GC for real-time needs.

Why use String over &str in Rust?

String for mutable, heap-grown text. &str for static, immutable slices.
