Struct rustc_infer::traits::ImplDerivedCause

pub struct ImplDerivedCause<'tcx> {
    pub derived: DerivedCause<'tcx>,
    pub impl_or_alias_def_id: DefId,
    pub impl_def_predicate_index: Option<usize>,
    pub span: Span,
}

Fields

derived: DerivedCause<'tcx>

impl_or_alias_def_id: DefId

The DefId of the impl that gave rise to the derived obligation. If the derived obligation arose from a trait alias, which conceptually has a synthetic impl, then this will be the DefId of that trait alias. Care should therefore be taken to handle that exceptional case where appropriate.

impl_def_predicate_index: Option<usize>

The index of the derived predicate in the parent impl’s predicates.

span: Span

Trait Implementations

impl<'tcx> Clone for ImplDerivedCause<'tcx>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for ImplDerivedCause<'tcx>

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

Formats the value using the given formatter.

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

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

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

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

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

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

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

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

impl<'tcx> PartialEq for ImplDerivedCause<'tcx>

fn eq(&self, other: &ImplDerivedCause<'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 ImplDerivedCause<'tcx>

fn try_fold_with<__F>( self, __folder: &mut __F, ) -> Result<ImplDerivedCause<'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 ImplDerivedCause<'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 ImplDerivedCause<'tcx>

impl<'tcx> StructuralPartialEq for ImplDerivedCause<'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.
