Module structs

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
