Module itertools::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.
• CircularTupleWindows
  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.
• ConsTuples
  An iterator that maps an iterator of tuples like ((A, B), C) to an iterator of (A, B, C).
• ExactlyOneError
  Iterator returned for the error case of IterTools::exactly_one() This iterator yields exactly the same elements as the input iterator.
• FilterMapOk
  An iterator adapter to filter and apply a transformation on values within a nested Result::Ok.
• FilterOk
  An iterator adapter to filter values within a nested Result::Ok.
• FlattenOk
  An iterator adaptor that flattens Result::Ok values and allows Result::Err values through unchanged.
• Format
  Format all iterator elements lazily, separated by sep.
• FormatWith
  Format all iterator elements lazily, separated by sep.
• 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.
• IntersperseWith
  An iterator adaptor to insert a particular value created by a function between each element of the adapted iterator.
• Iterate
  An iterator that infinitely applies function to value and yields results.
• 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.
• 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.
• 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.
• TakeWhileInclusive
  An iterator adaptor that consumes elements while the given predicate is true, including the element for which the predicate first returned false.
• TakeWhileRef
  An iterator adaptor that borrows from a Clone-able iterator to only pick off elements while the predicate returns true.
• 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.
• 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

Type Aliases

• Coalesce
  An iterator adaptor that may join together adjacent elements.
• Dedup
  An iterator adaptor that removes repeated duplicates.
• DedupBy
  An iterator adaptor that removes repeated duplicates, determining equality using a comparison function.
• DedupByWithCount
  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.
• DedupWithCount
  An iterator adaptor that removes repeated duplicates, while keeping a count of how many repeated elements were present.
• Intersperse
  An iterator adaptor to insert a particular value between each element of the adapted iterator.
• MapInto
  An iterator adapter to apply Into conversion to each element.
• MapOk
  An iterator adapter to apply a transformation within a nested Result::Ok.
• MapResultsDeprecated
  See MapOk.
• Merge
  An iterator adaptor that merges the two base iterators in ascending order. If both base iterators are sorted (ascending), the result is sorted.
