Methods

impl<'cx, 'gcx, 'tcx> UniversalRegionsBuilder<'cx, 'gcx, 'tcx>

fn build(self) -> UniversalRegions<'tcx>

fn defining_ty(&self) -> DefiningTy<'tcx>

🔬 This is a nightly-only experimental API. (rustc_private)

Returns the "defining type" of the current MIR; see DefiningTy for details.

fn compute_indices(     &self,     fr_static: RegionVid,     defining_ty: DefiningTy<'tcx> ) -> UniversalRegionIndices<'tcx>

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Builds a hashmap that maps from the universal regions that are in scope (as a ty::Region<'tcx>) to their indices (as a RegionVid). The map returned by this function contains only the early-bound regions.

fn compute_inputs_and_output(     &self,     indices: &UniversalRegionIndices<'tcx>,     defining_ty: DefiningTy<'tcx> ) -> Binder<&'tcx List<Ty<'tcx>>>
