Type Alias rustc_infer::infer::outlives::env::RegionBoundPairs

pub type RegionBoundPairs<'tcx> = FxIndexSet<OutlivesPredicate<GenericKind<'tcx>, Region<'tcx>>>;

“Region-bound pairs” tracks outlives relations that are known to be true, either because of explicit where-clauses like T: 'a or because of implied bounds.

Aliased Type
