The concrete iterator types.
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.
- Chunk
- An iterator for the elements in a single chunk.
- ChunkBy
ChunkByis the storage for the lazy grouping operation.- Chunks
- An iterator that yields the Chunk iterators.
- Circular
Tuple Windows - An iterator over all windows, wrapping back to the first elements when the window would otherwise exceed the length of the iterator, producing tuples of a specific size.
- Combinations
With Replacement - An iterator to iterate through all the
n-length combinations in an iterator, with replacement. - Exactly
OneError - Iterator returned for the error case of
Itertools::exactly_one()This iterator yields exactly the same elements as the input iterator. - Filter
MapOk - An iterator adapter to filter and apply a transformation on values within a nested
Result::Ok. - Filter
Ok - An iterator adapter to filter values within a nested
Result::Ok. - Flatten
Ok - An iterator adaptor that flattens
Result::Okvalues and allowsResult::Errvalues through unchanged. - Format
- Format all iterator elements lazily, separated by
sep. - Format
With - Format all iterator elements lazily, separated by
sep. - Group
- An iterator for the elements in a single group.
- Grouping
Map GroupingMapis an intermediate struct for efficient group-and-fold operations. It groups elements by their key and at the same time fold each group using some aggregating operation.- Groups
- An iterator that yields the Group iterators.
- Interleave
- An iterator adaptor that alternates elements from two iterators until both run out.
- Interleave
Shortest - An iterator adaptor that alternates elements from the two iterators until one of them runs out.
- Intersperse
With - An iterator adaptor to insert a particular value created by a function between each element of the adapted iterator.
- Into
Chunks ChunkLazyis the storage for a lazy chunking operation.- Iterate
- An iterator that infinitely applies function to value and yields results.
- KMerge
By - An iterator adaptor that merges an abitrary number of base iterators according to an ordering function.
- MergeBy
- An iterator adaptor that merges the two base iterators in ascending order. If both base iterators are sorted (ascending), the result is sorted.
- Multi
Peek - See
multipeek()for more information. - Multi
Product - An iterator adaptor that iterates over the cartesian product of
multiple iterators of type
I. - PadUsing
- An iterator adaptor that pads a sequence to a minimum length by filling missing elements using a closure.
- PeekNth
- See
peek_nth()for more information. - Peeking
Take While - An iterator adaptor that takes items while a closure returns
true. - Permutations
- An iterator adaptor that iterates through all the
k-permutations of the elements from an iterator. - Positions
- An iterator adapter to get the positions of each element that matches a predicate.
- Powerset
- An iterator to iterate through the powerset of the elements from an iterator.
- Process
Results - An iterator that produces only the
Tvalues as long as the inner iterator producesOk(T). - Product
- An iterator adaptor that iterates over the cartesian product of
the element sets of two iterators
IandJ. - PutBack
- An iterator adaptor that allows putting back a single item to the front of the iterator.
- PutBackN
- An iterator adaptor that allows putting multiple items in front of the iterator.
- RcIter
- A wrapper for
Rc<RefCell<I>>, that implements theIteratortrait. - RepeatN
- An iterator that produces n repetitions of an element.
- Take
While Inclusive - An iterator adaptor that consumes elements while the given predicate is
true, including the element for which the predicate first returnedfalse. - Take
While Ref - An iterator adaptor that borrows from a
Clone-able iterator to only pick off elements while the predicate returnstrue. - Tee
- One half of an iterator pair where both return the same elements.
- Tuple
Buffer - An iterator over a incomplete tuple.
- Tuple
Combinations - An iterator to iterate through all combinations in a
Clone-able iterator that produces tuples of a specific size. - Tuple
Windows - An iterator over all contiguous windows that produces tuples of a specific size.
- Tuples
- An iterator that groups the items in tuples of a specific size.
- Unfold
Deprecated - See
unfoldfor more information. - Unique
- An iterator adapter to filter out duplicate elements.
- Unique
By - An iterator adapter to filter out duplicate elements.
- Update
- An iterator adapter to apply a mutating function to each element before yielding it.
- While
Some - An iterator adaptor that filters
Option<A>iterator elements and producesA. Stops on the firstNoneencountered. - With
Position - An iterator adaptor that wraps each element in an
Position. - Zip
- See
multizipfor more information. - ZipEq
- An iterator which iterates two other iterators simultaneously and panic if they have different lengths.
- ZipLongest
- An iterator which iterates two other iterators simultaneously
and wraps the elements in
EitherOrBoth.
Type Aliases§

Combinations - Iterator for const generic combinations returned by
.array_combinations() - Coalesce

((A, B), C)to an iterator of(A, B, C). - Dedup
- An iterator adaptor that removes repeated duplicates.
- DedupBy
- An iterator adaptor that removes repeated duplicates, determining equality using a comparison function.

ByWith Count - 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.
