    <(_:_:)

    Returns a Boolean value indicating whether the first tuple is ordered before the second in a lexicographical ordering.

    func < <A, B, C, D>(lhs: (A, B, C, D), rhs: (A, B, C, D)) -> Bool where A : Comparable, B : Comparable, C : Comparable, D : Comparable

    Parameters

    lhs

    A tuple of Comparable elements.

    rhs

    Another tuple of elements of the same type as lhs.

    Overview

    Given two tuples (a1, a2, ..., aN) and (b1, b2, ..., bN), the first tuple is before the second tuple if and only if a1 < b1 or (a1 == b1 and (a2, ..., aN) < (b2, ..., bN)).
