operator==(ranges::join_view::iterator, ranges::join_view::sentinel)

friend constexpr bool operator==( const /*iterator*/<Const>& x, const /*sentinel*/& y );
(since C++20)

Compares the underlying iterator of x with the underlying sentinel of y.

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when join_view::sentinel<Const> is an associated class of the arguments.

The != operator is synthesized from operator==.


x - iterator to compare
y - sentinel to compare

Return value

x.current_ == y.end_, where current_ denotes the underlying iterator, end_ denotes the underlying sentinel.
