friend void swap( std::copyable_function & lhs, std::copyable_function & rhs ) noexcept;
(since C++26)
Overloads the std::swap algorithm for std::copyable_function. Exchanges the state of lhs with that of rhs. Effectively calls lhs.swap(rhs).
This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::copyable_function<FunctionType> is an associated class of the arguments.
