std::swap

std::hash

 

template< class T, class Deleter > void swap( unique_ptr<T,Deleter>& lhs, unique_ptr<T,Deleter>& rhs ) noexcept;		(since C++11)

Specializes the std::swap algorithm for std::unique_ptr. Swaps the pointers of lhs and rhs. Calls lhs.swap(rhs).

This function does not participate in overload resolution unless std::is_swappable<D>::value is true.

(since C++17)

Parameters

lhs, rhs

-

smart pointers whose contents to swap

Return value

(none)

Complexity

Constant
