[][src]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.

Coalesce

An iterator adaptor that may join together adjacent elements.

ConsTuples

An iterator that maps an iterator of tuples like ((A, B), C) to an iterator of (A, B, C).

DedupBy

An iterator adaptor that removes repeated duplicates, determining equality using a comparison function.

ExactlyOneError

Iterator returned for the error case of IterTools::exactly_one() This iterator yields exactly the same elements as the input iterator.

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.

Intersperse

An iterator adaptor to insert a particular value between each element of the adapted iterator.

Iterate

An iterator that infinitely applies function to value and yields results.

MapInto

An iterator adapter to apply Into conversion to each element.

MapResults

An iterator adapter to apply a transformation within a nested Result.

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.

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 Definitions

Dedup

An iterator adaptor that removes repeated duplicates.

Merge

An iterator adaptor that merges the two base iterators in ascending order. If both base iterators are sorted (ascending), the result is sorted.
