Trait Implementations

impl<'tcx> Clone for ValuePairs<'tcx>

pub fn clone(&self) -> ValuePairs<'tcx>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx> Copy for ValuePairs<'tcx>

impl<'tcx> Debug for ValuePairs<'tcx>

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'tcx> Eq for ValuePairs<'tcx>

impl<'tcx> PartialEq<ValuePairs<'tcx>> for ValuePairs<'tcx>

pub fn eq(&self, other: &ValuePairs<'tcx>) -> bool

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

pub fn ne(&self, other: &ValuePairs<'tcx>) -> bool

This method tests for !=.

impl<'tcx> StructuralEq for ValuePairs<'tcx>

impl<'tcx> StructuralPartialEq for ValuePairs<'tcx>

impl<'tcx> TypeFoldable<'tcx> for ValuePairs<'tcx>

pub fn super_fold_with<__F: TypeFolder<'tcx>>(self, __folder: &mut __F) -> Self

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

pub fn fold_with<F>(self, folder: &mut F) -> Self where
    F: TypeFolder<'tcx>, 

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

pub 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.

pub 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).

pub fn has_escaping_bound_vars(&self) -> bool

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

pub fn has_projections(&self) -> bool

pub fn has_opaque_types(&self) -> bool

pub fn references_error(&self) -> bool

pub fn has_param_types_or_consts(&self) -> bool

pub fn has_infer_regions(&self) -> bool

pub fn has_infer_types(&self) -> bool

pub fn has_infer_types_or_consts(&self) -> bool

pub fn needs_infer(&self) -> bool

pub fn has_placeholders(&self) -> bool

pub fn needs_subst(&self) -> bool

pub 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.

pub fn has_erased_regions(&self) -> bool

pub fn has_erasable_regions(&self) -> bool

True if there are any un-erased free regions.

pub 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.

pub fn has_late_bound_regions(&self) -> bool

True if there are any late-bound regions

pub 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.
