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

Consumers may find this more convenient to use with infallible folders than try_super_fold_with, to which the provided default definition delegates. Implementors should not override this provided default definition, to ensure that the two methods are coherent (provide a definition of try_super_fold_with instead).

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

Consumers may find this more convenient to use with infallible folders than try_fold_with, to which the provided default definition delegates. Implementors should not override this provided default definition, to ensure that the two methods are coherent (provide a definition of try_fold_with instead).

fn try_fold_with<F: FallibleTypeFolder<'tcx>>(

    folder: &mut F
) -> Result<Self, F::Error>

    &self,
    visitor: &mut V
) -> ControlFlow<V::BreakTy>

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 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.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
