Trait Implementations

impl<I> Clone for ExternalConstraintsData<I>

where I: Interner,

fn clone(&self) -> ExternalConstraintsData<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I> Debug for ExternalConstraintsData<I>

where I: Interner,

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

Formats the value using the given formatter.

impl<I> Default for ExternalConstraintsData<I>

where I: Interner,

fn default() -> ExternalConstraintsData<I>

Returns the “default value” for a type.

impl<I> Hash for ExternalConstraintsData<I>

where I: Interner,

fn hash<__HI>(&self, __state: &mut __HI)

where __HI: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<I, __CTX> HashStable<__CTX> for ExternalConstraintsData<I>

where I: Interner, Vec<OutlivesPredicate<I, <I as Interner>::GenericArg>>: HashStable<__CTX>, Vec<(OpaqueTypeKey<I>, <I as Interner>::Ty)>: HashStable<__CTX>, NestedNormalizationGoals<I>: HashStable<__CTX>,

fn hash_stable( &self, __hcx: &mut __CTX, __hasher: &mut StableHasher<SipHasher128>, )

impl<I> PartialEq for ExternalConstraintsData<I>

where I: Interner,

fn eq(&self, other: &ExternalConstraintsData<I>) -> bool

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<I> TypeFoldable<I> for ExternalConstraintsData<I>

where I: Interner, Vec<OutlivesPredicate<I, <I as Interner>::GenericArg>>: TypeFoldable<I>, Vec<(OpaqueTypeKey<I>, <I as Interner>::Ty)>: TypeFoldable<I>, NestedNormalizationGoals<I>: TypeFoldable<I>,

fn try_fold_with<__F>( self, __folder: &mut __F, ) -> Result<ExternalConstraintsData<I>, <__F as FallibleTypeFolder<I>>::Error>

where __F: FallibleTypeFolder<I>,

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

fn fold_with<F>(self, folder: &mut F) -> Self

where F: TypeFolder<I>,

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

impl<I> TypeVisitable<I> for ExternalConstraintsData<I>

where I: Interner, Vec<OutlivesPredicate<I, <I as Interner>::GenericArg>>: TypeVisitable<I>, Vec<(OpaqueTypeKey<I>, <I as Interner>::Ty)>: TypeVisitable<I>, NestedNormalizationGoals<I>: TypeVisitable<I>,

fn visit_with<__V>( &self, __visitor: &mut __V, ) -> <__V as TypeVisitor<I>>::Result

where __V: TypeVisitor<I>,

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

impl<I> Eq for ExternalConstraintsData<I>

where I: Interner,

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.
