Trait rustc_mir_build::thir::util::UserAnnotatedTyHelpers

pub(crate) trait UserAnnotatedTyHelpers<'tcx> {
    // Required methods
    fn tcx(&self) -> TyCtxt<'tcx>;
    fn typeck_results(&self) -> &TypeckResults<'tcx>;

}

Required Methods

fn tcx(&self) -> TyCtxt<'tcx>

fn typeck_results(&self) -> &TypeckResults<'tcx>

Provided Methods

fn user_args_applied_to_ty_of_hir_id( &self, hir_id: HirId ) -> Option<CanonicalUserType<'tcx>>

Looks up the type associated with this hir-id and applies the user-given substitutions; the hir-id must map to a suitable type.
