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

friend constexpr bool
    operator==( const /*iterator*/& x, const /*iterator*/& y ) noexcept;
(1) (since C++23)
friend constexpr std::strong_ordering
    operator<=>( const /*iterator*/& x, const /*iterator*/& y ) noexcept;
(2) (since C++23)

Compares the underlying iterators. Let pos_ be the underlying index.

1) Equivalent to return x.pos_ == y.pos_;.
2) Equivalent to return x.pos_ <=> y.pos_;.

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

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

Parameters

x, y - iterators to compare

Return value

Result of comparison.
