swap(std::mdspan)

friend constexpr void swap( mdspan& x, mdspan& y ) noexcept;

Overloads the std::swap algorithm for std::mdspan. Exchanges the state of x with that of y. Equivalent to:

std::swap(x.acc_,y.acc_);
std::swap(x.map_,y.map_);
std::swap(x.ptr_,y.ptr_);

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::mdspan is an associated class of the arguments.
