struct Zip2Generator<Generator1 : GeneratorType, Generator2 : GeneratorType> A generator for Zip2Sequence. Inheritance GeneratorType View Protocol Hierarchy → Associated Types Element = (Generator1.Element, Generator2.Element) The type of element returned by next(). Import import Swift Initializers init(_:_:) Construct around a pair of underlying generators. Declaration init(_ generator1: Generator1, _ generator2: Generator2) Instance Methods mutating func next() Advance to the next element and return it, or nil if no next element exists. Requires: next() has not been applied to a copy of self since the copy was made, and no preceding call to self.next() has returned nil. Declaration mutating func next() -> (Generator1.Element, Generator2.Element)?
