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.

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
