Type Alias itertools::adaptors::coalesce::DedupByWithCount
source · pub type DedupByWithCount<I, Pred> = CoalesceBy<I, DedupPredWithCount2CoalescePred<Pred>, WithCount>;
Expand description
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)
.
