There's a difference between a value being null, and a pointer being null. While Rust disallows both, it handles the cases differently; for the latter, a Rust program containing only safe Rust cannot create "null" references. However, for a "nullable" type, Rust encourages using `Option`, and forces you to handle the `null`/`None` case via a check.
