Function rustc_query_impl::make_query::erase_regions_ty

pub fn erase_regions_ty<'tcx>(
    tcx: QueryCtxt<'tcx>, 
    key: erase_regions_ty<'tcx>
) -> QueryStackFrame

Erases regions from ty to yield a new type. Normally you would just use tcx.erase_regions(value), however, which uses this query as a kind of cache.
