	operator	operator
	```c++ template<class Key, class Hash, class Pred, class Alloc> bool operator==(const unordered_set<Key, Hash, Pred, Alloc>& x, const unordered_set<Key, Hash, Pred, Alloc>& y); ```	```c++ template<class key,="" class="" hash,="" pred,="" alloc=""> bool operator==(const unordered_set<key, hash,="" pred,="" alloc="">& x, const unordered_set<key, hash,="" pred,="" alloc="">& y); ```</key,></key,></class>
	Return `true` if `x.size() == y.size()` and for every element in `x`, there is an element in `y` with the same key, with an equal value (using `operator==` to compare the value types).	如果 `x.size() == y.size()` 且对于 `x` 中的每个元素，在 `y` 中均存在一个具有相同键且值相等（使用 `operator==` 比较值类型）的元素，则返回 `true`。
:1438	Notes:;; Behavior is undefined if the two containers don't have equivalent equality predicates.	说明：如果两个容器的相等谓词不等价，则行为未定义。

	```c++ template<class Key, class Hash, class Pred, class Alloc> bool operator!=(const unordered_set<Key, Hash, Pred, Alloc>& x, const unordered_set<Key, Hash, Pred, Alloc>& y); ```	```c++ template<class key,="" class="" hash,="" pred,="" alloc=""> bool operator!=(const unordered_set<key, hash,="" pred,="" alloc="">& x, const unordered_set<key, hash,="" pred,="" alloc="">& y); ```</key,></key,></class>
	Return `false` if `x.size() == y.size()` and for every element in `x`, there is an element in `y` with the same key, with an equal value (using `operator==` to compare the value types).	如果 `x.size() == y.size()` 且对于 `x` 中的每个元素，在 `y` 中均存在一个具有相同键且值相等（使用 `operator==` 比较值类型）的元素，则返回 `false`。
:1452	Notes:;; Behavior is undefined if the two containers don't have equivalent equality predicates.	注意：如果两个容器的相等谓词不等价，则行为未定义。
:1454	---	---
	Swap	交换
	```c++ template<class Key, class Hash, class Pred, class Alloc> void swap(unordered_set<Key, Hash, Pred, Alloc>& x, unordered_set<Key, Hash, Pred, Alloc>& y) noexcept(noexcept(x.swap(y))); ```	```c++ template<class key,="" class="" hash,="" pred,="" alloc=""> void swap(unordered_set<key, hash,="" pred,="" alloc="">& x, unordered_set<key, hash,="" pred,="" alloc="">& y) noexcept(noexcept(x.swap(y))); ```</key,></key,></class>
	Swaps the contents of `x` and `y`.	交换 `x` 和 `y` 的内容。
:1466	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.	如果 `Allocator::propagate_on_container_swap` 已声明且 `Allocator::propagate_on_container_swap::value` 为 `true`，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。
	Effects:;; `x.swap(y)` Throws:;; Doesn't throw an exception unless it is thrown by the copy constructor or copy assignment operator of `key_equal` or `hasher`. Notes:;; The exception specifications aren't quite the same as the C++11 standard, as the equality predicate and hash function are swapped using their copy constructors.	效果：`x.swap(y)` 抛出：除非 `key_equal` 或 `hasher` 的复制构造函数或复制赋值运算符抛出异常，否则不会抛出异常。注意：由于相等谓词和哈希函数是通过它们的复制构造函数进行交换的，因此异常规范与 C++11 标准并不完全相同。
:1473	---	---
	erase_if	erase_if
	```c++ template<class K, class H, class P, class A, class Predicate> typename unordered_set<K, H, P, A>::size_type erase_if(unordered_set<K, H, P, A>& c, Predicate pred); ```	```c++ template<class k,="" class="" h,="" p,="" a,="" predicate=""> typename unordered_set<k, h,="" p,="" a="">::size_type erase_if(unordered_set<k, h,="" p,="" a="">& c, Predicate pred); ```</k,></k,></class>
	Traverses the container `c` and removes all elements for which the supplied predicate returns `true`.	遍历容器 `c`，并移除所有使得给定谓词返回 `true` 的元素。
	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(); ```	返回：被擦除的元素数量。注意：等价于：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();
	Serialization	序列化
	``unordered_set``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++_++set` 可通过本库提供的 API，借助 link:../../../../../serialization/index.html[Boost.Serialization] 实现序列化存档与读取功能。同时支持常规格式与 XML 格式的归档。
	Saving an unordered_set to an archive	将 unordered++_++set 保存到归档
	Saves all the elements of an `unordered_set` `x` to an archive (XML archive) `ar`.	将 `unordered++_++set` 对象 `x` 的所有元素保存到归档（XML 归档） `ar` 中。
	Requires:;; `value_type` is serializable (XML serializable), and it supports 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;; `value++_++type` 必须可序列化（支持 XML 序列化），且需要支持 Boost.Serialization 的 `save++_++construct++_++data` / `load++_++construct++_++data` 协议（该协议自动支持满足 https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[可默认构造] 要求的类型）。
:1517	---	---
	Loading an unordered_set from an archive	从归档加载 unordered++_++set
	Deletes all preexisting elements of an `unordered_set` `x` and inserts from an archive (XML archive) `ar` restored copies of the elements of the original `unordered_set` `other` saved to the storage read by `ar`.	删除 `unordered++_++set` 对象 `x` 的所有预先存在的元素，并从归档（XML 归档） `ar` 中读取原始 `unordered++_++set` 对象 `other` 先前保存至存储的元素副本并插入到 `x` 中。
	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/MoveInsertable[MoveInsertable^]. `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` 需满足 https://en.cppreference.com/w/cpp/named_req/MoveInsertable[可移动插入] 要求，且 `x.key++_++equal()` 在功能上需等价于 `other.key++_++equal()` 。注意;; 若归档文件是使用 Boost 1.84 之前的版本保存的，则必须全局定义配置宏 `BOOST++_++UNORDERED++_++ENABLE++_++SERIALIZATION++_++COMPATIBILITY++_++V0` 才能成功执行此操作；否则将抛出异常。
