pub(crate) struct RegionErrors<'tcx>(Vec<(RegionErrorKind<'tcx>, ErrorGuaranteed)>, TyCtxt<'tcx>);Expand description
A collection of errors encountered during region inference. This is needed to efficiently report errors after borrow checking.
Usually we expect this to either be empty or contain a small number of items, so we can avoid allocation most of the time.
