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.
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.
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.
KMergeBy
An iterator adaptor that merges an abitrary number of base iterators according to an ordering function.
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.
MergeJoinBy
An iterator adaptor that merge-joins items from the two base iterators in ascending order.
MultiPeek
See multipeek() for more information.
MultiProduct
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.
PeekingTakeWhile
An iterator adaptor that takes items while a closure returns true.
Positions
An iterator adapter to get the positions of each element that matches a predicate.
ProcessResults
An iterator that produces only the T values as long as the inner iterator produces Ok(T).
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.
RepeatCallDeprecated
See repeat_call for more information.
RepeatN
An iterator that produces n repetitions of an element.
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.
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.
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.
WithPosition
An iterator adaptor that wraps each element in an Position.
Zip
See multizip for more information.
ZipEq
An iterator which iterates two other iterators simultaneously
ZipLongest
An iterator which iterates two other iterators simultaneously
