operator==,<=>(ranges::zip_view::iterator)

friend constexpr bool operator==( const /*iterator*/& x, const /*iterator*/& y )
  requires (std::equality_comparable<
    ranges::iterator_t</*maybe-const*/<Const, Views>>> && ...);

friend constexpr auto operator<=>( const /*iterator*/& x, const /*iterator*/& y )
  requires ranges::random_access_range<Base>;

Compares the underlying iterators.

Let current_ be the underlying tuple-like object of iterators to elements of adapted views.

• x.current_ == y.current_ if /*all-bidirectional*/<Const, Views...> is true.
• Otherwise, true if there exists an integer 0 <= i < sizeof...(Views) such that bool(std::get<i>(x.current_) == std::get<i>(y.current_)) is true.
• Otherwise, false.

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::ranges::zip_view::iterator<Const> is an associated class of the arguments.

The <, <=, >, >=, and != operators are synthesized from operator<=> and operator== respectively.

Parameters

Return value

The result of comparison.
