Struct rustc_middle::traits::ImplSourceObjectData

pub struct ImplSourceObjectData<'tcx, N> {
    pub upcast_trait_ref: PolyTraitRef<'tcx>,
    pub vtable_base: usize,
    pub nested: Vec<N>,
}

Fields

upcast_trait_ref: PolyTraitRef<'tcx>

Foo upcast to the obligation trait. This will be some supertrait of Foo.

vtable_base: usize

The vtable is formed by concatenating together the method lists of the base object trait and all supertraits, pointers to supertrait vtable will be provided when necessary; this is the start of upcast_trait_ref’s methods in that vtable.

nested: Vec<N>

    __hasher: &mut StableHasher
)

fn lift_to_tcx(
    self,
    __tcx: TyCtxt<'__lifted>
) -> Option<ImplSourceObjectData<'__lifted, N::Lifted>>

impl<'tcx, N: PartialEq> PartialEq<ImplSourceObjectData<'tcx, N>> for ImplSourceObjectData<'tcx, N>

fn eq(&self, other: &ImplSourceObjectData<'tcx, N>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ImplSourceObjectData<'tcx, N>) -> bool

This method tests for !=.

impl<'tcx, N> TypeFoldable<'tcx> for ImplSourceObjectData<'tcx, N> where
    N: TypeFoldable<'tcx>, 

fn try_super_fold_with<__F: FallibleTypeFolder<'tcx>>(
    self,
    __folder: &mut __F
) -> Result<Self, __F::Error>

Traverses the type in question, typically by calling try_fold_with on each field/element. This is true even for types of interest such as Ty. This should only be called within TypeFolder methods, when non-custom traversals are desired for types of interest.

fn super_visit_with<__F: TypeVisitor<'tcx>>(
    &self,
    __folder: &mut __F
) -> ControlFlow<__F::BreakTy>

Traverses the type in question, typically by calling visit_with on each field/element. This is true even for types of interest such as Ty. This should only be called within TypeVisitor methods, when non-custom traversals are desired for types of interest.

fn try_fold_with<F: FallibleTypeFolder<'tcx>>(
    self,
    folder: &mut F
) -> Result<Self, F::Error>

The main entry point for folding. To fold a value t with a folder f call: t.try_fold_with(f).

fn fold_with<F: TypeFolder<'tcx, Error = !>>(self, folder: &mut F) -> Self

A convenient alternative to try_fold_with for use with infallible folders. Do not override this method, to ensure coherence with try_fold_with.

fn super_fold_with<F: TypeFolder<'tcx, Error = !>>(self, folder: &mut F) -> Self

A convenient alternative to try_super_fold_with for use with infallible folders. Do not override this method, to ensure coherence with try_super_fold_with.

fn visit_with<V: TypeVisitor<'tcx>>(
    &self,
    visitor: &mut V
) -> ControlFlow<V::BreakTy>

The entry point for visiting. To visit a value t with a visitor v call: t.visit_with(v).

fn has_vars_bound_at_or_above(&self, binder: DebruijnIndex) -> bool

Returns true if self has any late-bound regions that are either bound by binder or bound by some binder outside of binder. If binder is ty::INNERMOST, this indicates whether there are any late-bound regions that appear free.

fn has_vars_bound_above(&self, binder: DebruijnIndex) -> bool

Returns true if this self has any regions that escape binder (and hence are not bound by it).

fn has_escaping_bound_vars(&self) -> bool

fn has_type_flags(&self, flags: TypeFlags) -> bool

fn has_projections(&self) -> bool

fn has_opaque_types(&self) -> bool

fn references_error(&self) -> bool

fn error_reported(&self) -> Option<ErrorGuaranteed>

fn has_param_types_or_consts(&self) -> bool

fn has_infer_regions(&self) -> bool

fn has_infer_types(&self) -> bool

fn has_infer_types_or_consts(&self) -> bool

fn needs_infer(&self) -> bool

fn has_placeholders(&self) -> bool

fn needs_subst(&self) -> bool

fn has_free_regions(&self) -> bool

“Free” regions in this context means that it has any region that is not (a) erased or (b) late-bound.

fn has_erased_regions(&self) -> bool

fn has_erasable_regions(&self) -> bool

True if there are any un-erased free regions.

fn is_global(&self) -> bool

Indicates whether this value references only ‘global’ generic parameters that are the same regardless of what fn we are in. This is used for caching.

fn has_late_bound_regions(&self) -> bool

True if there are any late-bound regions

fn still_further_specializable(&self) -> bool

Indicates whether this value still has parameters/placeholders/inference variables which could be replaced later, in a way that would change the results of impl specialization.
