Trait Implementations

impl<'tcx> Clone for InternedObligationCauseCode<'tcx>

fn clone(&self) -> InternedObligationCauseCode<'tcx>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for InternedObligationCauseCode<'tcx>

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

Formats the value using the given formatter.

impl<'tcx, __D> Decodable<__D> for InternedObligationCauseCode<'tcx>

where __D: TyDecoder<I = TyCtxt<'tcx>>,

fn decode(__decoder: &mut __D) -> InternedObligationCauseCode<'tcx>

impl<'tcx> Default for InternedObligationCauseCode<'tcx>

fn default() -> InternedObligationCauseCode<'tcx>

Returns the “default value” for a type.

impl<'tcx> Deref for InternedObligationCauseCode<'tcx>

type Target = ObligationCauseCode<'tcx>

The resulting type after dereferencing.

fn deref(&self) -> &ObligationCauseCode<'tcx>

Dereferences the value.

impl<'tcx, __E> Encodable<__E> for InternedObligationCauseCode<'tcx>

where __E: TyEncoder<I = TyCtxt<'tcx>>,

fn encode(&self, __encoder: &mut __E)

impl<'tcx, '__ctx> HashStable<StableHashingContext<'__ctx>> for InternedObligationCauseCode<'tcx>

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher<SipHasher128>, )

impl<'tcx> PartialEq for InternedObligationCauseCode<'tcx>

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl<'tcx> TypeFoldable<TyCtxt<'tcx>> for InternedObligationCauseCode<'tcx>

fn try_fold_with<__F>( self, __folder: &mut __F, ) -> Result<InternedObligationCauseCode<'tcx>, <__F as FallibleTypeFolder<TyCtxt<'tcx>>>::Error>

where __F: FallibleTypeFolder<TyCtxt<'tcx>>,

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<'tcx> TypeVisitable<TyCtxt<'tcx>> for InternedObligationCauseCode<'tcx>

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

where __V: TypeVisitor<TyCtxt<'tcx>>,

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

impl<'tcx> Eq for InternedObligationCauseCode<'tcx>

impl<'tcx> StructuralPartialEq for InternedObligationCauseCode<'tcx>

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.
