fn is_maybe_dangling(tcx: TyCtxt<'_>, did: DefId) -> bool
Expand description

Whether did is the MaybeDangling lang item.

The MaybeDangling lang item was only added to rustc’s table after nightly-2026-02-05 (the verify-std toolchain), so gate the lang-item lookup behind a build-time check and fall back to name matching on toolchains that lack it.
