Type Definition itertools::structs::DedupByWithCount

#[must_use = "iterator adaptors are lazy and do nothing unless consumed"]type DedupByWithCount<I, Pred> = CoalesceBy<I, DedupPredWithCount2CoalescePred<Pred>, (usize, <I as Iterator>::Item)>;

An iterator adaptor that removes repeated duplicates, while keeping a count of how many repeated elements were present. This will determine equality using a comparison function.

See .dedup_by_with_count() or .dedup_with_count() for more information.
