constexpr void swap(basic_string& s) noexcept(allocator_traits<Allocator>::propagate_on_container_swap::value || allocator_traits<Allocator>::is_always_equal::value);
Preconditions: allocator_traits::propagate_on_container_swap::value is true orget_allocator() == s.get_allocator().
Postconditions: this contains the same sequence of characters that was in s,s contains the same sequence of characters that was inthis.
Throws: Nothing.
Complexity: Constant time.
