:996	Erase the element pointed to by `position`.	擦除 `position` 所指向的元素。
:999	Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`. + + In this implementation, this overload doesn't call either function object's methods so it is no throw, but this might not be true in other implementations. Notes:;; This method was implemented because returning an iterator to the next element from erase was expensive, but the container has been redesigned so that is no longer the case. So this method is now deprecated.	抛出：仅当 `hasher` 或 `key_equal` 抛出异常时才会抛出。在此实现中，此重载不会调用任何函数对象的方法，因此不会抛出异常，但这在其他实现中可能并不成立。注意：引入此方法是因为从 `erase` 返回指向下一个元素的迭代器成本较高，但容器已经过重新设计，不再存在这种情况。因此，此方法现已弃用。
:1004	---	---
	swap	交换
	```c++ void swap(unordered_multiset&) noexcept(boost::allocator_traits<Allocator>::is_always_equal::value && boost::is_nothrow_swappable_v<Hash> && boost::is_nothrow_swappable_v<Pred>); ```	```c++ void swap(unordered_multiset&) noexcept(boost::allocator_traits<allocator>::is_always_equal::value && boost::is_nothrow_swappable_v<hash> && boost::is_nothrow_swappable_v<pred>); ```</pred></hash></allocator>
	Swaps the contents of the container with the parameter.	交换容器的内容与参数的内容。
:1016	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` 被声明且 `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。
	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.	抛出：除非 `key_equal` 或 `hasher` 的拷贝构造函数或拷贝赋值运算符抛出异常，否则不抛出任何异常。注意：异常规范与 C++11 标准不完全相同，因为相等谓词和哈希函数是使用其拷贝构造函数进行交换的。
:1022	---	---
	clear	清空
	```c++ void clear() noexcept; ```	```c++ void clear() noexcept; ```
	Erases all elements in the container.	擦除容器中的所有元素。
	Postconditions:;; `size() == 0` Throws:;; Never throws an exception.	后置条件：`size() == 0` 抛出：永不抛出异常。
:1035	---	---
	merge	合并
	```c++ template<class H2, class P2> void merge(unordered_multiset<Key, H2, P2, Allocator>& source); template<class H2, class P2> void merge(unordered_multiset<Key, H2, P2, Allocator>&& source); template<class H2, class P2> void merge(unordered_set<Key, H2, P2, Allocator>& source); template<class H2, class P2> void merge(unordered_set<Key, H2, P2, Allocator>&& source); ```	```c++ template<class h2,="" class="" p2=""> void merge(unordered_multiset<key, h2,="" p2,="" allocator="">& source); template<class h2,="" class="" p2=""> void merge(unordered_multiset<key, h2,="" p2,="" allocator="">&& source); template<class h2,="" class="" p2=""> void merge(unordered_set<key, h2,="" p2,="" allocator="">& source); template<class h2,="" class="" p2=""> void merge(unordered_set<key, h2,="" p2,="" allocator="">&& source); ```</key,></class></key,></class></key,></class></key,></class>
	Attempt to "merge" two containers by iterating `source` and extracting all nodes in `source` and inserting them into `*this`.	尝试“合并”两个容器：遍历 `source`，提取 `source` 中的所有节点，并将它们插入到 `*this` 中。
	Because `source` can have a different hash function and key equality predicate, the key of each node in `source` is rehashed using `this\->hash_function()` and then, if required, compared using `this\->key_eq()`.	由于 `source` 可能具有不同的哈希函数和键相等谓词，因此 `source` 中每个节点的键都会使用 `this->hash_function()` 重新计算哈希值，然后在必要时使用 `this->key_eq()` 进行比较。
	The behavior of this function is undefined if `this\->get_allocator() != source.get_allocator()`.	如果 `this->get_allocator() != source.get_allocator()`，则此函数的行为未定义。
	This function does not copy or move any elements and instead simply relocates the nodes from `source` into `*this`.	此函数不会拷贝或移动任何元素，而是仅仅将节点从 `source` 重新定位到 `*this` 中。
	Notes:;; + --	注意:;; + --
	Pointers and references to transferred elements remain valid.	指向被转移元素的指针和引用保持有效。
	Invalidates iterators to transferred elements.	使指向被转移元素的迭代器失效。
	Invalidates iterators belonging to `*this`.	使属于 `*this` 的迭代器失效。
	Iterators to non-transferred elements in `source` remain valid.	指向 `source` 中未被转移元素的迭代器保持有效。

	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/MoveInsertable[MoveInsertable^]. Returns:;; An iterator pointing to the inserted element. Throws:;; If an exception is thrown by an operation other than a call to `hasher` the function has no effect. Notes:;; Can invalidate iterators, but only if the insert causes the load factor to be greater to or equal to the maximum load factor. + + Pointers and references to elements are never invalidated.	要求：`value_type` 满足 https://en.cppreference.com/w/cpp/named_req/MoveInsertable[可移动插入^]。返回：指向已插入元素的迭代器。抛出：如果除调用 `hasher` 之外的操作抛出异常，则该函数无效果。注意：可能使迭代器失效，但仅当插入导致负载因子大于或等于最大负载因子时才会发生。指向元素的指针和引用永远不会失效。
	Copy Insert with Hint	带提示的复制插入

	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/CopyInsertable[CopyInsertable^]. Returns:;; An iterator pointing to the inserted element. Throws:;; If an exception is thrown by an operation other than a call to `hasher` the function has no effect. Notes:;; The standard is fairly vague on the meaning of the hint. But the only practical way to use it, and the only way that Boost.Unordered supports is to point to an existing element with the same key. + + Can invalidate iterators, but only if the insert causes the load factor to be greater to or equal to the maximum load factor. + + Pointers and references to elements are never invalidated.	要求：`value_type` 满足 https://en.cppreference.com/w/cpp/named_req/CopyInsertable[可拷贝插入^]。返回：指向已插入元素的迭代器。抛出：如果除调用 `hasher` 之外的操作抛出异常，则该函数无效果。注意：标准关于 `hint` 的含义表述相当模糊。但唯一实际的使用方式，也是 Boost.Unordered 支持的唯一方式，是将其指向一个具有相同键的已存在元素。可能使迭代器失效，但仅当插入导致负载因子大于或等于最大负载因子时才会发生。指向元素的指针和引用永远不会失效。
	Insert with Hint and `node_handle`	带提示和 `node_handle` 的插入
	```c++ iterator insert(const_iterator hint, node_type&& nh); ```	```c++ iterator insert(const_iterator hint, node_type&& nh); ```
	Returns:;; The iterator following `position` before the erasure. Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`. Notes:;; In older versions this could be inefficient because it had to search through several buckets to find the position of the returned iterator. The data structure has been changed so that this is no longer the case, and the alternative erase methods have been deprecated.	返回：`position` 在被擦除之前的后一个迭代器。抛出：仅当 `hasher` 或 `key_equal` 抛出异常时才会抛出。注意：在旧版本中，此操作可能效率较低，因为它需要搜索多个桶以找到返回迭代器的位置。数据结构已经更改，不再是这种情况，并且备用的擦除方法已被弃用。
