Trait CollectLifetimes

    // Required methods
    fn collect_lifetimes<'a>(
        self,
        options: &Options,
        lifetimes: &'a 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<'a>( 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.
