std::extents<IndexType,Extents...>::dynamic-index-inv

private:
    template< class OtherIndexType >
    static constexpr auto /*dynamic-index-inv*/( rank_type i ) noexcept;

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

Return value

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