	Deletes all preexisting elements of an `unordered_multimap` `x` and inserts from an archive (XML archive) `ar` restored copies of the elements of the original `unordered_multimap` `other` saved to the storage read by `ar`.	删除 `unordered_multimap` 容器 `x` 中所有已存在的元素，并从归档（XML 归档）`ar` 中插入从原始 `unordered_multimap` 容器 `other` 保存到 `ar` 所读取存储中的元素恢复出的副本。
	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[EmplaceConstructible^] from `(std::remove_const<key_type>::type&&, std::remove_const<mapped_type>::type&&)`. `x.key_equal()` is functionally equivalent to `other.key_equal()`. Note:;; If the archive was saved using a release of Boost prior to Boost 1.84, the configuration macro `BOOST_UNORDERED_ENABLE_SERIALIZATION_COMPATIBILITY_V0` has to be globally defined for this operation to succeed; otherwise, an exception is thrown.	要求：`value_type` 必须可以从 `(std::remove_const<key_type>::type&&, std::remove_const<mapped_type>::type&&)` 进行 https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[可原位构造^]。`x.key_equal()` 在功能上必须等价于 `other.key_equal()`。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。</mapped_type></key_type>
	Saving an iterator/const_iterator to an archive	将迭代器/常量迭代器保存到归档

	Loading an iterator/const_iterator from an archive	从归档加载迭代器/常量迭代器
