fn to_program_clauses( &self, builder: &mut ClauseBuilder<'_, I>, _environment: &Environment<I>, )
Given the following type definition: struct Foo<T: Eq> { }
, generate:
-- Rule WellFormed-Type
forall<T> {
WF(Foo<T>) :- WF(T: Eq).
}
-- Rule Implied-Bound-From-Type
forall<T> {
FromEnv(T: Eq) :- FromEnv(Foo<T>).
}
forall<T> {
IsFullyVisible(Foo<T>) :- IsFullyVisible(T).
}
If the type Foo
is marked #[upstream]
, we also generate:
forall<T> { IsUpstream(Foo<T>). }
Otherwise, if the type Foo
is not marked #[upstream]
, we generate:
forall<T> { IsLocal(Foo<T>). }
Given an #[upstream]
type that is also fundamental:
#[upstream]
#[fundamental]
struct Box<T, U> {}
We generate the following clauses:
forall<T, U> { IsLocal(Box<T, U>) :- IsLocal(T). }
forall<T, U> { IsLocal(Box<T, U>) :- IsLocal(U). }
forall<T, U> { IsUpstream(Box<T, U>) :- IsUpstream(T), IsUpstream(U). }
// Generated for both upstream and local fundamental types
forall<T, U> { DownstreamType(Box<T, U>) :- DownstreamType(T). }
forall<T, U> { DownstreamType(Box<T, U>) :- DownstreamType(U). }

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
