	Serialization	序列化
	``unordered_map``s can be archived/retrieved by means of link:../../../../../serialization/index.html[Boost.Serialization^] using the API provided by this library. Both regular and XML archives are supported.	`unordered_map` 可以通过本库提供的 API，使用 link:../../../../../serialization/index.html[Boost.Serialization^] 进行归档/恢复。支持常规归档和 XML 归档。
	Saving an unordered_map to an archive	将 unordered_map 保存到归档
	Saves all the elements of an `unordered_map` `x` to an archive (XML archive) `ar`.	将 `unordered_map` `x` 的所有元素保存到归档（XML 归档）`ar` 中。
	Requires:;; `std::remove_const<key_type>::type` and `std::remove_const<mapped_type>::type` are serializable (XML serializable), and they do support Boost.Serialization `save_construct_data`/`load_construct_data` protocol (automatically suported by https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[DefaultConstructible^] types).	要求：;; `std::remove_const<key_type>::type` 和 `std::remove_const<mapped_type>::type` 必须是可序列化的（支持 XML 序列化），并且它们支持 Boost.Serialization 的 `save_construct_data`/`load_construct_data` 协议（该协议由 https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[DefaultConstructible^] 类型的自动支持）。</mapped_type></key_type>

	Loading an unordered_map from an archive	从归档中加载 unordered_map
	Deletes all preexisting elements of an `unordered_map` `x` and inserts from an archive (XML archive) `ar` restored copies of the elements of the original `unordered_map` `other` saved to the storage read by `ar`.	删除 `unordered_map` `x` 中所有已存在的元素，并从归档（XML 归档）`ar` 中插入由 `ar` 所读取存储中保存的原始 `unordered_map` `other` 元素的恢复副本。
	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` 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[EmplaceConstructible^]。`x.key_equal()` 在功能上等价于 `other.key_equal()`。注意：;; 如果归档是使用 Boost 1.84 之前的 Boost 版本保存的，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中
	Saves the positional information of an `iterator` (`const_iterator`) `it` to an archive (XML archive) `ar`. `it` can be and `end()` iterator.	将 `iterator`（`const_iterator`）`it` 的位置信息保存到归档（XML 归档）`ar` 中。`it` 可以是 `end()` 迭代器。
	Requires:;; The `unordered_map` `x` pointed to by `it` has been previously saved to `ar`, and no modifying operations have been issued on `x` between saving of `x` and saving of `it`.	要求：;; `it` 所指向的 `unordered_map` `x` 此前已保存至 `ar`，并且在保存 `x` 和保存 `it` 之间未对 `x` 执行任何修改操作。

	Loading an iterator/const_iterator from an archive	从归档中加载迭代器/常量迭代器
	Makes an `iterator` (`const_iterator`) `it` point to the restored position of the original `iterator` (`const_iterator`) saved to the storage read by an archive (XML archive) `ar`.	使 `iterator`（`const_iterator`）`it` 指向保存到由归档（XML 归档）`ar` 读取的存储中的原始 `iterator`（`const_iterator`）的被恢复位置。
	Requires:;; If `x` is the `unordered_map` `it` points to, no modifying operations have been issued on `x` between loading of `x` and loading of `it`.	要求：;; 如果 `x` 是 `it` 所指向的 `unordered_map`，则在加载 `x` 和加载 `it` 之间未对 `x` 执行任何修改操作。

	Returns:;; The number of erased elements. Notes:;; Equivalent to: + + ```c++ auto original_size = c.size(); for (auto i = c.begin(), last = c.end(); i != last; ) { if (pred(*i)) { i = c.erase(i); } else { ++i; } } return original_size - c.size(); ``` + Note that the references passed to `pred` are non-const.	返回：;; 被移除的元素数量。备注：;; 等价于：```c++auto original_size = c.size();for (auto i = c.begin(), last = c.end(); i != last; ) { if (pred(*i)) { i = c.erase(i); } else { ++i; }}return original_size - c.size();```注意，传递给 `pred` 的引用是非常量的。
