std::deque<T,Allocator>::swap

void swap( deque& other );		(until C++17)
void swap( deque& other ) noexcept(/* see below */);		(since C++17)

Exchanges the contents of the container with those of other. Does not invoke any move, copy, or swap operations on individual elements.

All iterators and references remain valid. The past-the-end iterator is invalidated.

If std::allocator_traits<allocator_type>::propagate_on_container_swap::value is true, then the allocators are exchanged using an unqualified call to non-member swap. Otherwise, they are not swapped (and if get_allocator() != other.get_allocator(), the behavior is undefined). (since C++11)

Parameters

container to exchange the contents with

Return value

(none).

Exceptions

`noexcept` specification: `noexcept(std::allocator_traits<Allocator>::is_always_equal::value)`	(since C++17)
