Returns a list of potentially relevant impls for a given
trait-id; we also supply the type parameters that we are
trying to match (if known: these parameters may contain
inference variables, for example). The implementor is
permitted to return any superset of the applicable impls;
chalk will narrow down the list to only those that truly
apply. The parameters are provided as a “hint” to help the
implementor do less work, but can be completely ignored if
desired. Read more

fn split_projection<'p>( &self, projection: &'p ProjectionTy<I>, ) -> (Arc<AssociatedTyDatum<I>>, &'p [GenericArg<I>], &'p [GenericArg<I>])
Given a projection of an associated type, split the type
parameters into those that come from the trait and those
that come from the associated type itself. So e.g. if you
have
(Iterator::Item)<F>
, this would return ([F], [])
,
since Iterator::Item
is not generic and hence doesn’t have
any type parameters itself.source§fn trait_parameters_from_projection<'p>(
