Ownership
Understand Rust's core idea: every value has one owner.
📖 Key ideas
- Each value has a single owner.
- When the owner goes out of scope, the value is dropped.
- Assigning a String moves ownership: let b = a; (a is no longer valid).
- Clone makes a deep copy: let b = a.clone();
- Simple Copy types (integers, bool) are copied, not moved.
💡 Real-life example: Ownership is like a library book: only one person holds it; to give it away you hand it over.
