Implementations

impl<'tcx> UniversalRegionRelationsBuilder<'_, 'tcx>

fn relate_universal_regions(&mut self, fr_a: RegionVid, fr_b: RegionVid)

Records in the outlives_relation (and inverse_outlives_relation) that fr_a: fr_b.

pub(crate) fn create(self) -> CreateResult<'tcx>

fn normalize_and_push_type_outlives_obligation( &self, outlives: PolyTypeOutlivesPredicate<'tcx>, span: Span, known_type_outlives_obligations: &mut Vec<PolyTypeOutlivesPredicate<'tcx>>, constraints: &mut Vec<&QueryRegionConstraints<'tcx>>, )

fn add_implied_bounds( &mut self, ty: Ty<'tcx>, span: Span, ) -> Option<&'tcx QueryRegionConstraints<'tcx>>

Compute and add any implied bounds that come from a given type.

fn add_outlives_bounds<I>(&mut self, outlives_bounds: I)

where I: IntoIterator<Item = OutlivesBound<'tcx>>,

Registers the OutlivesBound items from outlives_bounds in the outlives relation as well as the region-bound pairs listing.

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.
