Trait Implementations

impl<I: Clone + Interner> Clone for ImplDatum<I>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I: Debug + Interner> Debug for ImplDatum<I>

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

Formats the value using the given formatter.

impl<I: Hash + Interner> Hash for ImplDatum<I>

fn hash<__H: Hasher>(&self, state: &mut __H)

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: PartialEq + Interner> PartialEq for ImplDatum<I>

fn eq(&self, other: &ImplDatum<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: Interner> RenderAsRust<I> for ImplDatum<I>

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

fn display<'a>( &'a self, s: &'a InternalWriterState<'a, I> ) -> DisplayRenderAsRust<'a, I, Self>

where Self: Sized,

impl<I: Interner> ToProgramClauses<I> for ImplDatum<I>

fn to_program_clauses( &self, builder: &mut ClauseBuilder<'_, I>, _environment: &Environment<I> )

Given impl<T: Clone> Clone for Vec<T> { ... }, generate:

-- Rule Implemented-From-Impl
forall<T> {
    Implemented(Vec<T>: Clone) :- Implemented(T: Clone).
}

For a negative impl like impl... !Clone for ..., however, we generate nothing – this is just a way to opt out from the default auto trait impls, it doesn’t have any positive effect on its own.

impl<I: Interner> TypeVisitable<I> for ImplDatum<I>

fn visit_with<B>( &self, visitor: &mut dyn TypeVisitor<I, BreakTy = B>, outer_binder: DebruijnIndex ) -> ControlFlow<B>

Apply the given visitor visitor to self; binders is the number of binders that are in scope when beginning the visitor. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs.
