#15322) Use `Box::as_non_null` method (added in #15321) to ensure that creating an `Address` from a `Box`, no intermediate reference to the contents of the `Box` is created. This is important in `Traverse` which has tight aliasing constraints. Possibly `addr_of!` macro we used previously already ensured this, but I'm not 100% sure due to the double deref (`**`). Using `Box::as_non_null` is unambiguously safe.

The benchmark results (+3% on minifier[cal.com.tsx]) are erroneous. Just noise. |
