Struct rustc_trait_selection::infer::free_regions::RegionRelations

pub struct RegionRelations<'a, 'tcx> {
    pub tcx: TyCtxt<'tcx>,
    pub context: DefId,
    pub free_regions: &'a FreeRegionMap<'tcx>,
}

Combines a FreeRegionMap and a TyCtxt.

This stuff is a bit convoluted and should be refactored, but as we transition to NLL, it'll all go away anyhow.

Fields

tcx: TyCtxt<'tcx>

context: DefId

The context used for debug messages

free_regions: &'a FreeRegionMap<'tcx>

Free-region relationships.

Implementations

impl<'a, 'tcx> RegionRelations<'a, 'tcx>

pub fn new(
    tcx: TyCtxt<'tcx>,
    context: DefId,
    free_regions: &'a FreeRegionMap<'tcx>
) -> RegionRelations<'a, 'tcx>

pub fn lub_free_regions(
    &self,
    r_a: &'tcx RegionKind,
    r_b: &'tcx RegionKind
) -> &'tcx RegionKind
