:888	Inserts a range of elements into the container. Elements are inserted if and only if there is no element in the container with an equivalent key.	将一个范围内的元素插入容器中。当且仅当容器中没有具有等价键的元素时，才会插入这些元素。
	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[EmplaceConstructible^] into the container from `*first`. Throws:;; When inserting a single element, 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 to be greater than the maximum load.	要求：`value_type` 可以从 `*first` 出发在容器中进行 https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[可原位构造^]。抛出：当插入单个元素时，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大于最大负载时才会发生。

Throws:;; When inserting a single element, 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 to be greater than the maximum load.	要求：`value_type` 可以在容器中进行 https://en.cppreference.com/w/cpp/named_req/CopyInsertable[可拷贝插入^]。抛出：当插入单个元素时，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大于最大负载时才会发生。

	Insert Node	节点插入
	```c++ insert_return_type insert(node_type&& nh); ```	```c++ insert_return_type insert(node_type&& nh); ```
	If `nh` is not empty, inserts the associated element in the container if and only if there is no element in the container with a key equivalent to `nh.value()`. `nh` is empty when the function returns.	如果 `nh` 非空，则当且仅当容器中没有键与 `nh.value()` 等价的元素时，才将关联的元素插入容器。函数返回时 `nh` 变为空。
	Returns:;; An `insert_return_type` object constructed from `position`, `inserted` and `node`: +	返回：一个 `insert_return_type` 对象，由 `position`、`inserted` 和 `node` 构造而成：
	If `nh` is empty, `inserted` is `false`, `position` is `end()`, and `node` is empty.	若 `nh` 为空，则 `inserted` 为 `false` ， `position` 为 `end()` ，且 `node` 为空。
	Otherwise if the insertion took place, `inserted` is true, `position` points to the inserted element, and `node` is empty.	否则，若插入操作发生，则 `inserted` 为 `true` ， `position` 指向被插入的元素，且 `node` 为空。
	If the insertion failed, `inserted` is false, `node` has the previous value of `nh`, and `position` points to an element with a key equivalent to `nh.value()`.	若插入操作失败，则 `inserted` 为 `false` ， `node` 保留 `nh` 的原始值，且 `position` 指向一个键等价于 `nh.value()` 的元素。
	Throws:;; If an exception is thrown by an operation other than a call to `hasher` the function has no effect. Notes:;; Behavior is undefined if `nh` is not empty and the allocators of `nh` and the container are not equal.	如果 `nh` 非空，则当且仅当容器中不存在键等价于 `nh.value()` 的元素时，插入其关联的元素。函数返回时， `nh` 为空。
:927	---	---
	Insert Node with Hint	带提示的节点插入
	```c++ iterator insert(const_iterator hint, node_type&& nh); ```	```c++ iterator insert(const_iterator hint, node_type&& nh); ```
	If `nh` is not empty, inserts the associated element in the container if and only if there is no element in the container with a key equivalent to `nh.value()`. `nh` becomes empty if insertion took place, otherwise it is not changed.	如果 `nh` 非空，则当且仅当容器中没有键与 `nh.value()` 等价的元素时，才将关联的元素插入容器。如果插入发生，则 `nh` 变为空；否则 `nh` 不变。
:937	`hint` is a suggestion to where the element should be inserted. This implementation ignores it.	`hint` 是关于元素插入位置的建议。此实现会忽略该建议。
	Returns:;; The iterator returned is `end()` if `nh` is empty. If insertion took place, then the iterator points to the newly inserted element; otherwise, it points to the element with equivalent key. Throws:;; If an exception is thrown by an operation other than a call to `hasher` the function has no effect. Notes:;; Behavior is undefined if `nh` is not empty and the allocators of `nh` and the container are not equal.	返回：如果 `nh` 为空，则返回的迭代器为 `end()`。如果插入发生，则迭代器指向新插入的元素；否则，指向具有等价键的元素。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：如果 `nh` 非空且 `nh` 与容器的分配器不相等，则行为未定义。
:945	---	---
	Erase by Position	通过位置擦除
	Erase the element pointed to by `position`.	擦除由 `position` 指向的元素。
	Returns:;; An opaque object implicitly convertible to the `iterator` or `const_iterator` immediately following `position` prior to the erasure. Throws:;; Nothing. Notes:;; The opaque object returned must only be discarded or immediately converted to `iterator` or `const_iterator`.	返回;; 返回一个不透明对象，该对象可隐式转换为擦除前紧接在 `position` 之后的 `iterator` 或 `const++_++iterator` 。抛出;; 无。注意;; 返回的不透明对象必须被立即丢弃或转换为 `iterator` 或 `const++_++iterator` 。

	Erase by Key	通过键擦除
	```c++ size_type erase(const key_type& k); template<class K> size_type erase(K&& k); ```	```c++ size_type erase(const key_type& k); template<class k=""> size_type erase(K&& k); ```</class>
	Erase all elements with key equivalent to `k`.	擦除所有键与 `k` 等价的元素。

	pull	pull
	```c++ init_type pull(const_iterator position); ```	```c++ init_type pull(const_iterator position); ```
	Returns:;; A range containing all elements with key equivalent to `k`. If the container doesn't contain any such elements, returns `std::make_pair(b.end(), b.end())`. Notes:;; The `template<class K>` overloads only participate in overload resolution if `Hash::is_transparent` and `Pred::is_transparent` are valid member typedefs. The library assumes that `Hash` is callable with both `K` and `Key` and that `Pred` is transparent. This enables heterogeneous lookup which avoids the cost of instantiating an instance of the `Key` type.	返回：包含所有键与 `k` 等价的元素的范围。如果容器不包含任何此类元素，则返回 `std::make_pair(b.end(), b.end())`。注意：`template<class k="">` 重载仅在 `Hash::is_transparent` 和 `Pred::is_transparent` 是有效的成员 typedef 时参与重载决议。库假定 `Hash` 可同时使用 `K` 和 `Key` 调用，且 `Pred` 是透明的。这支持了异构查找，从而避免了实例化 `Key` 类型对象的开销。</class>
