Struct rustc_borrowck::universal_regions::UniversalRegionsBuilder

struct UniversalRegionsBuilder<'cx, 'tcx> {
    infcx: &'cx InferCtxt<'cx, 'tcx>,
    mir_def: WithOptConstParam<LocalDefId>,
    mir_hir_id: HirId,
    param_env: ParamEnv<'tcx>,
}

Fields

infcx: &'cx InferCtxt<'cx, 'tcx>

mir_def: WithOptConstParam<LocalDefId>

mir_hir_id: HirId

param_env: ParamEnv<'tcx>

Implementations

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

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

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

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>

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, &'tcx List<Ty<'tcx>>>

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.
