pub(crate) struct RegionErrors<'tcx>(Vec<RegionErrorKind<'tcx>>, 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.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
