struct ReverseBidirectionalIndex<I : BidirectionalIndexType> A wrapper for a BidirectionalIndexType that reverses its direction of traversal Inheritance BidirectionalIndexType, Equatable, ForwardIndexType, _BidirectionalIndexType, _ForwardIndexType, _Incrementable View Protocol Hierarchy → Import import Swift Instance Methods func predecessor() Returns the previous consecutive value before self. Requires: the previous value is representable. Declaration func predecessor() -> ReverseBidirectionalIndex<I> func successor() Returns the next consecutive value after self. Requires: the next value is representable. Declaration func successor() -> ReverseBidirectionalIndex<I>
