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.

Parameters

lhs, rhs - std::copyable_function objects whose states to swap

Return value

(none)
