std::vector::swap

From cppreference.com

void swap( vector& other );

Exchanges the contents of the container with those of other.

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

The behavior is undefined if get_allocator() != other.get_allocator() and std::allocator_traits<allocator_type>::propagate_on_container_swap::value != true.
