Struct rustc_middle::traits::ImplSourceUserDefinedData

pub struct ImplSourceUserDefinedData<'tcx, N> {
    pub impl_def_id: DefId,
    pub args: GenericArgsRef<'tcx>,
    pub nested: Vec<N>,
}

Identifies a particular impl in the source, along with a set of substitutions from the impl’s type/lifetime parameters. The nested vector corresponds to the nested obligations attached to the impl’s type parameters.

The type parameter N indicates the type used for “nested obligations” that are required by the impl. During type-check, this is Obligation, as one might expect. During codegen, however, this is (), because codegen only requires a shallow resolution of an impl, and nested obligations are satisfied later.

Fields

impl_def_id: DefId

args: GenericArgsRef<'tcx>

nested: Vec<N>

Trait Implementations

impl<'tcx, N: Clone> Clone for ImplSourceUserDefinedData<'tcx, N>

fn clone(&self) -> ImplSourceUserDefinedData<'tcx, N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx, N: Debug> Debug for ImplSourceUserDefinedData<'tcx, N>

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

Formats the value using the given formatter.

impl<'tcx, N, __D: TyDecoder<I = TyCtxt<'tcx>>> Decodable<__D> for ImplSourceUserDefinedData<'tcx, N>where N: Decodable<__D>,

fn decode(__decoder: &mut __D) -> Self

impl<'tcx, N, __E: TyEncoder<I = TyCtxt<'tcx>>> Encodable<__E> for ImplSourceUserDefinedData<'tcx, N>where N: Encodable<__E>,

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

impl<'tcx, '__ctx, N> HashStable<StableHashingContext<'__ctx>> for ImplSourceUserDefinedData<'tcx, N>where N: HashStable<StableHashingContext<'__ctx>>,

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

impl<'tcx, N: PartialEq> PartialEq<ImplSourceUserDefinedData<'tcx, N>> for ImplSourceUserDefinedData<'tcx, N>

fn eq(&self, other: &ImplSourceUserDefinedData<'tcx, N>) -> 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<'tcx, N> TypeFoldable<TyCtxt<'tcx>> for ImplSourceUserDefinedData<'tcx, N>where N: TypeFoldable<TyCtxt<'tcx>>,

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

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) -> Selfwhere 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, N> TypeVisitable<TyCtxt<'tcx>> for ImplSourceUserDefinedData<'tcx, N>where N: TypeVisitable<TyCtxt<'tcx>>,

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

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

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.
