Module iter

Structs

• Chain
  An iterator that links two iterators together, in a chain.
• Cloned
  An iterator that clones the elements of an underlying iterator.
• Copied
  An iterator that copies the elements of an underlying iterator.
• Cycle
  An iterator that repeats endlessly.
• Empty
  An iterator that yields nothing.
• Enumerate
  An iterator that yields the current count and the element during iteration.
• Filter
  An iterator that filters the elements of iter with predicate.
• FilterMap
  An iterator that uses f to both filter and map elements from iter.
• FlatMap
  An iterator that maps each element to an iterator, and yields the elements of the produced iterators.
• Flatten
  An iterator that flattens one level of nesting in an iterator of things that can be turned into iterators.
• FromFn
  An iterator where each iteration calls the provided closure F: FnMut() -> Option<T>.
• Fuse
  An iterator that yields None forever after the underlying iterator yields None once.
• Inspect
  An iterator that calls a function with a reference to each element before yielding it.
• Map
  An iterator that maps the values of iter with f.
• MapWhile
  An iterator that only accepts elements while predicate returns Some(_).
• Once
  An iterator that yields an element exactly once.
• OnceWith
  An iterator that yields a single element of type A by applying the provided closure F: FnOnce() -> A.
• Peekable
  An iterator with a peek() that returns an optional reference to the next element.
• Repeat
  An iterator that repeats an element endlessly.
• RepeatN
  An iterator that repeats an element an exact number of times.
• RepeatWith
  An iterator that repeats elements of type A endlessly by applying the provided closure F: FnMut() -> A.
• Rev
  A double-ended iterator with the direction inverted.
• Scan
  An iterator to maintain state while iterating another iterator.
• Skip
  An iterator that skips over n elements of iter.
• SkipWhile
  An iterator that rejects elements while predicate returns true.
• StepBy
  An iterator for stepping iterators by a custom amount.
• Successors
  A new iterator where each successive item is computed based on the preceding one.
• Take
  An iterator that only iterates over the first n iterations of iter.
• TakeWhile
  An iterator that only accepts elements while predicate returns true.
• Zip
  An iterator that iterates two other iterators simultaneously.
• ArrayChunksExperimental
  An iterator over N elements of the iterator at a time.
• ByRefSizedExperimental
  Like Iterator::by_ref, but requiring Sized so it can forward generics.
• IntersperseExperimental
  An iterator adapter that places a separator between all elements.
• IntersperseWithExperimental
  An iterator adapter that places a separator between all elements.
• MapWindowsExperimental
  An iterator over the mapped windows of another iterator.

Traits

• Iterator
  A trait for dealing with iterators.
• Product
  Trait to represent types that can be created by multiplying elements of an iterator.
• Sum
