constexpr size_type size() const noexcept;		(since C++23)

Returns the number of elements in mdspan.

Equivalent to extents().fwd-prod-of-extents(rank()).

If the size of the multidimensional index space extents() is not representable as a value of type size_type, the behavior of the program is undefined.

Parameters

(none)

Return value

The number of elements.
