Struct rustc_infer::infer::free_regions::RegionRelations

source · 
pub(crate) struct RegionRelations<'a, 'tcx> {
    pub tcx: TyCtxt<'tcx>,
    pub free_regions: &'a FreeRegionMap<'tcx>,
}
Expand description

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>§free_regions: &'a FreeRegionMap<'tcx>

Free-region relationships.
