Calculates the distance (in number of underlying elements) between the iterator and sentinel

Let parent_ be the underlying pointer to the enclosing chunk_view.

1) Equivalent to:
return ranges::min (i.parent_ - >remainder_,
ranges::end (i.parent_ - >base_) - *i.parent_ - >current_) ;
2) Equivalent to: return -(s - i);

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::ranges::chunk_view::inner-iterator

Parameters

i - the iterator
s - the sentinel

Return value

The distance between given iterator and sentinel.
