Trait Implementations

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

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

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

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

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

Formats the value using the given formatter. Read more

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

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

Feeds this value into the given Hasher. Read more

1.3.0 · source

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

Feeds a slice of this type into the given Hasher. Read more

impl<I: PartialEq + Interner> PartialEq<ImplDatum<I>> 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 ==. Read more

fn ne(&self, other: &ImplDatum<I>) -> bool

This method tests for !=.

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> Visit<I> for ImplDatum<I>

fn visit_with<B>(
    &self,
    visitor: &mut dyn Visitor<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. Read more
