std::ranges::join_view
friend constexpr bool operator== ( const /*iterator*/ & x, const /*iterator*/ & y )

requires
/*ref-is-glvalue*/ &&
std::equality_comparable < ranges::iterator_t <Base>> &&

std::equality_comparable < ranges::iterator_t < ranges::range_reference_t <Base>>> ;
(since C++20)

Compares the underlying iterators.

Equivalent to: return (x.outer_ == y.outer_ ) and (x.inner_ == y.inner_ ) ; , where outer_ and inner_ are the underlying iterators. The constant /*ref-is-glvalue*/ in the requires-clause is equal to std::is_reference_v < ranges::range_reference_t <Base>>

The != operator is synthesized from operator==.

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::ranges::join_view::iterator<Const>

Parameters

x, y - iterators to compare

Return value

Result of comparison.
