Construct an iterator. Overloads (3,4) are called by begin() and end() of ranges::join_with_view.

Overload	Data members
	parent_	outer_it_	inner_it_
(1)	initialized with nullptr	value-initialized (only if Base models forward_range)	default-initialized
(2)	initialized with i.parent_	initialized with std::move(i.outer_it_  (only if Base models forward_range)
(3)	initialized with  std::addressof(parent)	initialized with std::move(outer)
(4)		N/A

2) After initializing the data members, equivalent to

if (i.inner_it_ .index() == 0)
    inner_it_ .template emplace<0>(std::get<0>(std::move(i.inner_it_ )));
else
    inner_it_ .template emplace<1>(std::get<1>(std::move(i.inner_it_ )));

.

3,4) After initializing the data members, adjust the outer iterator as if the inner iterator was incremented by operator++().

Parameters

i	-	a mutable iterator
parent	-	a std::ranges::join_with_view object
outer	-	an iterator into the underlying range of parent
