self’s address as *mut Self for deferred-task / scopeguard /
ref_guard ctx slots. The closures/trampolines deref it as shared
(&*p) — every method they reach is &self post-R-2, so no write
provenance is required; the *mut spelling is purely to match the
existing DerefOnDrop / HasAutoFlush / RefCount ABI.Source§impl<T> BorrowMut<T> for Twhere
