swap (std::mdspan)

friend constexpr void swap ( mdspan & x, mdspan & y ) noexcept ;		(since C++23)

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.

Parameters
