Structs

Batching

A “meta iterator adaptor”. Its closure receives a reference to the iterator and may pick off as many elements as it likes, to produce the next iterator element.

Coalesce

An iterator adaptor that may join together adjacent elements.

CoalesceCore

Dedup

An iterator adaptor that removes repeated duplicates.

Interleave

An iterator adaptor that alternates elements from two iterators until both run out.

InterleaveShortest

An iterator adaptor that alternates elements from the two iterators until one of them runs out.

MapInto

An iterator adapter to apply Into conversion to each element.

MapResults

An iterator adapter to apply a transformation within a nested Result.

Merge

An iterator adaptor that merges the two base iterators in ascending order. If both base iterators are sorted (ascending), the result is sorted.

MergeBy

An iterator adaptor that merges the two base iterators in ascending order. If both base iterators are sorted (ascending), the result is sorted.

MergeCore 🔒

Positions

An iterator adapter to get the positions of each element that matches a predicate.

Product

An iterator adaptor that iterates over the cartesian product of the element sets of two iterators I and J.

PutBack

An iterator adaptor that allows putting back a single item to the front of the iterator.

StepDeprecated

An iterator adaptor that steps a number elements in the base iterator for each iteration.

TakeWhileRef

An iterator adaptor that borrows from a Clone-able iterator to only pick off elements while the predicate returns true.

Tuple1Combination

Tuple2Combination

Tuple3Combination

Tuple4Combination

TupleCombinations

An iterator to iterate through all combinations in a Clone-able iterator that produces tuples of a specific size.

Update

An iterator adapter to apply a mutating function to each element before yielding it.

WhileSome

An iterator adaptor that filters Option<A> iterator elements and produces A. Stops on the first None encountered.
