Searcher for finding type params in an iterator.

This trait extends iterators, providing a way to turn a filtered list of fields or variants into a set of type parameter idents.

Required Methods

fn collect_type_params<'a>( self, options: &Options, type_set: &'a HashSet<Ident, BuildHasherDefault<FnvHasher>>, ) -> HashSet<&'a Ident, BuildHasherDefault<FnvHasher>>

Consume an iterator, accumulating all type parameters in the elements which occur in type_set.

fn collect_type_params_cloned( self, options: &Options, type_set: &HashSet<Ident, BuildHasherDefault<FnvHasher>>, ) -> HashSet<Ident, BuildHasherDefault<FnvHasher>>

Consume an iterator using collect_type_params, then clone all found type params and return that set.
