Type Alias itertools::structs::DedupByWithCount

pub type DedupByWithCount<I, Pred> = CoalesceBy<I, DedupPredWithCount2CoalescePred<Pred>, WithCount>;

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.

Aliased Type

struct DedupByWithCount<I, Pred> {
    iter: I,
    last: Option<Option<<WithCount as CountItem<<I as Iterator>::Item>>::CItem>>,
    f: DedupPredWithCount2CoalescePred<Pred>,
}

Fields

iter: I

last: Option<Option<<WithCount as CountItem<<I as Iterator>::Item>>::CItem>>

last is None while no item have been taken out of iter (at definition). Then last will be Some(Some(item)) until iter is exhausted, in which case last will be Some(None).
