Type Definition rustc_mir::borrow_check::diagnostics::region_errors::RegionErrors

pub(crate) type RegionErrors<'tcx> = Vec<RegionErrorKind<'tcx>>;

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.
