compare(_:_:)

If lhs is ordered before rhs in the ordering described by the given sequence of SortComparators

Declaration

func compare<Comparator>(_ lhs: Comparator.Compared, _ rhs: Comparator.Compared) -> ComparisonResult where Comparator : SortComparator, Comparator == Self.Element

Discussion

The first element of the sequence of comparators specifies the primary comparator to be used in sorting the sequence’s elements. Any subsequent comparators are used to further refine the order of elements with equal values.
