template< bool OtherConst >

    requires std::sentinel_for<ranges::sentinel_t<Base>,
                               ranges::iterator_t<__maybe_const<OtherConst, V>>>
friend constexpr bool operator==( const /*iterator*/<OtherConst>& x,

                                  const /*sentinel*/& y );
(since C++23)

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

Equivalent to: return x.current_.back() == y.end_, where current_ is underlying array of iterators in x, and end_ is the underlying sentinel in y.

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

The != operator is synthesized from operator==.

[edit] Parameters

x - iterator to compare
y - sentinel to compare

[edit] Return value

true if the underlying iterator stored in x is the end iterator.
