注意：如果归档是使用 Boost 1.84 之前版本的 Boost 保存的，则必须全局定义配置宏 `BOOST_UNORDERED_ENABLE_SERIALIZATION_COMPATIBILITY_V0` 才能使此操作成功；否则，将抛出异常。

If `Allocator::propagate_on_container_swap` is declared and `Allocator::propagate_on_container_swap::value` is `true` then the containers' allocators are swapped. Otherwise, swapping with unequal allocators results in undefined behavior.
If如果 `Allocator::propagate_on_container_swap` is declared and被声明且 `Allocator::propagate_on_container_swap::value` is为 `true` then the containers' allocators are swapped. Otherwise, swapping with unequal allocators results in undefined behavior.，则交换容器的分配器。否则，使用不相等的分配器进行交换将导致未定义行为。
