private:     static constexpr auto /*dynamic-index-inv*/( rank_type i ) noexcept;		(since C++23) (exposition only*)

Returns the number r such that in range [​0​, r + 1) there are exactly [​0​, i + 1) dynamic extents. If i <= rank_dynamic() is false, the behavior is undefined.

Parameters

i

-

the index

Return value

The minimum value of r such that dynamic-index(r + 1) == i + 1 is true.
