Trait darling::usage::CollectLifetimes

pub trait CollectLifetimes {
    fn collect_lifetimes(
        self, 
        options: &Options, 
        lifetimes: &'a HashSet<Lifetime, BuildHasherDefault<FnvHasher>>
    ) -> HashSet<&'a Lifetime, BuildHasherDefault<FnvHasher>>;
    fn collect_lifetimes_cloned(

        lifetimes: &HashSet<Lifetime, BuildHasherDefault<FnvHasher>>
    ) -> HashSet<Lifetime, BuildHasherDefault<FnvHasher>>;
}

Searcher for finding lifetimes in an iterator.

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

Required methods

fn collect_lifetimes(
    self,
    options: &Options,
    lifetimes: &'a HashSet<Lifetime, BuildHasherDefault<FnvHasher>>
) -> HashSet<&'a Lifetime, BuildHasherDefault<FnvHasher>>

Consume an iterator, accumulating all lifetimes in the elements which occur in lifetimes.

fn collect_lifetimes_cloned(
    self,
    options: &Options,
    lifetimes: &HashSet<Lifetime, BuildHasherDefault<FnvHasher>>
) -> HashSet<Lifetime, BuildHasherDefault<FnvHasher>>

Consume an iterator using collect_lifetimes, then clone all found lifetimes and return that set.
