std::ranges::join_view::iterator(3)

NAME
std::ranges::join_view::iterator - std::ranges::join_view::iterator

Synopsis
   template< bool Const > (since C++20)
   class /*iterator*/ (exposition only*)
   The return type of join_view::begin, and of join_view::end when both the outer range
   V and the inner range ranges::range_reference_t<V> satisfy common_range and the
   parent join_view is a forward_range.
   If V is not a simple view (e.g. if ranges::iterator_t<const V> is invalid or
   different from ranges::iterator_t<V>), Const is true for iterators returned from the
   const overloads, and false otherwise. If V is a simple view, Const is true if and
   only if ranges::range_reference_t<V> is a reference.
