Struct rustc_infer::infer::error_reporting::nice_region_error::static_impl_trait::TraitObjectVisitor

pub(super) struct TraitObjectVisitor(pub(super) FxHashSet<DefId>);

Collect all the trait objects in a type that could have received an implicit 'static lifetime.

Trait Implementations

impl<'tcx> TypeVisitor<'tcx> for TraitObjectVisitor

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

Supplies the tcx for an unevaluated anonymous constant in case its default substs are not yet supplied.

fn visit_ty(&mut self, t: Ty<'tcx>) -> ControlFlow<Self::BreakTy>

type BreakTy = !

fn visit_binder<T>(&mut self, t: &Binder<T>) -> ControlFlow<Self::BreakTy, ()> where
    T: TypeFoldable<'tcx>, 

fn visit_region(&mut self, r: &RegionKind) -> ControlFlow<Self::BreakTy, ()>

fn visit_const(&mut self, c: &Const) -> ControlFlow<Self::BreakTy, ()>

fn visit_unevaluated_const(
    &mut self,
    uv: Unevaluated<Option<Promoted>>
) -> ControlFlow<Self::BreakTy, ()>

fn visit_predicate(&mut self, p: Predicate) -> ControlFlow<Self::BreakTy, ()>

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.
