Notes (These could be totally wrong!)

• Box<T> to allocate from heap.
• Rc<T> to share variable among multiple owners without lifetime parametes in a single threaded program. It only allows immutable access to data. Value needs to wrapped in RefCell<T> if mutability is desired.
• T.clone() does a deep copy. Avoid deep copy with Rc::clone(&T).
• RefCell<T> is used to mutate the value inside an immutable value. This is called interior mutability pattern. RefCell<T> inforces same borrow checking rules in runtime.
• Arc<T> to share T among multiple threads.

Q&A

• Is the data in Vec always densely packed?
• Serialize 'struct' with dynamically sized data to '&[u8]'?
