std::function
 
template< class R, class... Args >
void swap( function<R(Args...)> &lhs, function<R(Args...)> &rhs );
 (since C++11)
(until C++17)
template< class R, class... Args >
void swap( function<R(Args...)> &lhs, function<R(Args...)> &rhs ) noexcept;
 (since C++17)

Overloads the std::swap algorithm for std::function. Exchanges the state of lhs with that of rhs. Effectively calls lhs.swap(rhs).

Parameters

lhs, rhs - polymorphic function wrappers whose states to swap

Return value

(none)
