Structs

• IterChain
  🔄 core An iterator that links two iterators together, in a chain.
• IterCloned
  🔄 core An iterator that clones the elements of an underlying iterator.
• IterCopied
  🔄 core An iterator that copies the elements of an underlying iterator.
• IterCycle
  🔄 core An iterator that repeats endlessly.
• IterEmpty
  🔄 core An iterator that yields nothing.
• IterEnumerate
  🔄 core An iterator that yields the current count and the element during iteration.
• IterFilter
  🔄 core An iterator that filters the elements of iter with predicate.
• IterFilterMap
  🔄 core An iterator that uses f to both filter and map elements from iter.
• IterFlatMap
  🔄 core An iterator that maps each element to an iterator, and yields their elements.
• IterFlatten
  🔄 core An iterator that flattens one level of nesting in an iterator of iterables.
• IterFromFn
  🔄 core An iterator where each iteration calls a closure F: FnMut() -> Option<T>.
• IterFuse
  🔄 core An iterator that yields None forever after the underlying yields None once.

  🔄 core An iterator that calls a fn with a reference to each element before yielding it.
• IterMap
  🔄 core An iterator that maps the values of iter with f.
• IterMapWhile
  🔄 core An iterator that only accepts elements while predicate returns Some(_).
• IterOnce
  🔄 core An iterator that yields an element exactly once.
• IterOnceWith
  🔄 core An iterator that yields a single element A by calling F: FnOnce() -> A.
• IterPeekable
  🔄 core An iterator with a peek() that returns an optional ref to the next element.
• IterRepeat
  🔄 core An iterator that repeats an element endlessly.
• IterRepeatWith
  🔄 core An iterator that endlessly repeats A by calling F: FnMut() -> A.
• IterRev
  🔄 core A double-ended iterator with the direction inverted.
• IterScan
  🔄 core An iterator to maintain state while iterating another iterator.
• IterSkip
  🔄 core An iterator that skips over n elements of iter.
• IterSkipWhile
  🔄 core An iterator that rejects elements while predicate returns true.
• IterStepBy
  🔄 core An iterator for stepping iterators by a custom amount.
• IterSuccessors
  🔄 core An iterator where each successive item is computed based on the preceding one.
• IterTake
  🔄 core An iterator that only iterates over the first n iterations of iter.
• IterTakeWhile
  🔄 core An iterator that only accepts elements while predicate returns true.
• IterZip
  🔄 core An iterator that iterates two other iterators simultaneously.
