Module itertools::structs

The concrete iterator types.

Structs

Batching	A “meta iterator adaptor”. Its closure recives 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.
Chunks	An iterator that yields the Chunk iterators.
Coalesce	An iterator adaptor that may join together adjacent elements.
Combinations	An iterator to iterate through all the n-length combinations in an iterator.
ConsTuples	An iterator that maps an iterator of tuples like ((A, B), C) to an iterator of (A, B, C).
Dedup	An iterator adaptor that removes repeated duplicates.
Flatten	An iterator adapter to simply flatten a structure.
Format	Format all iterator elements lazily, separated by sep.
FormatWith	Format all iterator elements lazily, separated by sep.
Group	An iterator for the elements in a single group.
GroupBy	GroupBy is the storage for the lazy grouping operation.
Groups	An iterator that yields the Group iterators.
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.
Intersperse	An iterator adaptor to insert a particular value between each element of the adapted iterator.
IntoChunks	ChunkLazy is the storage for a lazy chunking operation.
Iterate	An iterator that infinitely applies function to value and yields results.
KMerge	An iterator adaptor that merges an abitrary number of base iterators in ascending order. If all base iterators are sorted (ascending), the result is sorted.
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.
MultiPeek	See multipeek() for more information.
PadUsing	An iterator adaptor that pads a sequence to a minimum length by filling missing elements using a closure.
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.
PutBackN	An iterator adaptor that allows putting multiple items in front of the iterator.
RcIter	A wrapper for Rc<RefCell<I>>, that implements the Iterator trait.
RepeatCall	See repeat_call for more information.
RepeatN	An iterator that produces n repetitions of an element.
Step	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.
Tee	One half of an iterator pair where both return the same elements.
TupleBuffer	An iterator over a incomplete tuple.
TupleCombinations	An iterator to iterate through all combinations in a Clone-able iterator that produces tuples of a specific size.
TupleWindows	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	See unfold for more information.
Unique	An iterator adapter to filter out duplicate elements.
UniqueBy	An iterator adapter to filter out duplicate elements.
WhileSome	An iterator adaptor that filters Option<A> iterator elements and produces A. Stops on the first None encountered.
Zip	See multizip for more information.
ZipEq	An iterator which iterates two other iterators simultaneously
ZipLongest	An iterator which iterates two other iterators simultaneously
