Struct rustc_typeck::check::Inherited

pub struct Inherited<'a, 'tcx> {
    pub(in check) infcx: InferCtxt<'a, 'tcx>,
    pub(in check) typeck_results: MaybeInProgressTables<'a, 'tcx>,
    pub(in check) locals: RefCell<HirIdMap<LocalTy<'tcx>>>,
    pub(in check) fulfillment_cx: RefCell<Box<dyn TraitEngine<'tcx>>>,
    pub(in check) deferred_sized_obligations: RefCell<Vec<(Ty<'tcx>, Span, ObligationCauseCode<'tcx>)>>,

    pub(in check) deferred_cast_checks: RefCell<Vec<CastCheck<'tcx>>>,

    pub(in check) body_id: Option<BodyId>,
}

Closures defined within the function. For example:

fn foo() {
    bar(move|| { ... })
}

Here, the function foo() and the closure passed to bar() will each have their own FnCtxt, but they will share the inherited fields.

Fields

infcx: InferCtxt<'a, 'tcx>

typeck_results: MaybeInProgressTables<'a, 'tcx>

locals: RefCell<HirIdMap<LocalTy<'tcx>>>

fulfillment_cx: RefCell<Box<dyn TraitEngine<'tcx>>>

deferred_sized_obligations: RefCell<Vec<(Ty<'tcx>, Span, ObligationCauseCode<'tcx>)>>

deferred_call_resolutions: RefCell<DefIdMap<Vec<DeferredCallResolution<'tcx>>>>

deferred_cast_checks: RefCell<Vec<CastCheck<'tcx>>>

deferred_generator_interiors: RefCell<Vec<(BodyId, Ty<'tcx>, GeneratorKind)>>

opaque_types: RefCell<DefIdMap<OpaqueTypeDecl<'tcx>>>

opaque_types_vars: RefCell<FxHashMap<Ty<'tcx>, Ty<'tcx>>>

A map from inference variables created from opaque type instantiations (ty::Infer) to the actual opaque type (ty::Opaque). Used during fallback to map unconstrained opaque type inference variables to their corresponding opaque type.

body_id: Option<BodyId>
