[−][src]Trait darling::usage::CollectTypeParams

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

    fn collect_type_params_cloned(

}

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(
    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.
