Deduction guides(C++17)

 

template< class T, class Container > void swap( queue<T,Container>& lhs,            queue<T,Container>& rhs );		(until C++17)
template< class T, class Container > void swap( queue<T,Container>& lhs,            queue<T,Container>& rhs ) noexcept(/* see below */);		(since C++17)

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

This overload only participates in overload resolution if std::is_swappable<Container>::value is true.

(since C++17)

Parameters

lhs, rhs

-

containers whose contents to swap

Return value

(none)

Complexity

Same as swapping the underlying container.

Exceptions

noexcept specification:   noexcept(noexcept(lhs.swap(rhs)))

(since C++17)
