This leads to somewhat ugly formatting:
&& let hir::Node::Item(hir::Item { kind: hir::ItemKind::Impl(impl_), .. }) =
self.tcx.hir_node(parent_hir_id)I think the current version is nicer, but I don’t feel that strong about it, so I can make this change if you prefer it.
It's only valid when applied to a type or lifetime parameter in `Drop` trait implementation.
