Chapter Key Takeaways

• Ownership rules ensure single ownership per resource and deterministic cleanup.
• Stack memory holds fixed-size data; heap memory holds dynamic data referenced via stack pointers.
• Move semantics transfer ownership, invalidating previous bindings to prevent double-free errors.
• Copy types duplicate automatically via bitwise copy; heap types require explicit .clone().
• The Drop trait executes custom cleanup when a value leaves scope.
