friend constexpr bool operator==( const /*iterator*/<Const>& x, const /*sentinel*/& y ); | (since C++23) |
Compares the underlying iterator of x with the underlying sentinel of y. The comparison returns true if the underlying outer iterator stored in x is the end iterator.
This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when join_with_view::sentinel<Const> is an associated class of the arguments.
The != operator is synthesized from operator==.
| x | - | iterator to compare |
| y | - | sentinel to compare |
x.outer_it_ == y.end_, where outer_it_ denotes the underlying outer iterator, end_ denotes the underlying sentinel.
