Deduction guides(C++17)

 

template< class R, class... Args > void swap( function<R(Args...)> &lhs, function<R(Args...)> &rhs );

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)

Exceptions

(none)	(until C++17)
noexcept specification:   noexcept	(since C++17)
