	rehash	重哈希
	```c++ void rehash(size_type n); ```	```c++ void rehash(size_type n); ```
	Changes if necessary the size of the bucket array so that there are at least `n` buckets, and so that the load factor is less than or equal to the maximum load factor. When applicable, this will either grow or shrink the `bucket_count()` associated with the table.	效果：;; 必要时调整桶数组的大小，使桶数量至少为 `n`，且负载因子小于等于最大负载因子。适用时，该操作会增大或缩小容器的桶数量 `bucket_count()`。
	When `size() == 0`, `rehash(0)` will deallocate the underlying buckets array.	效果：;; 当容器元素数量 `size() == 0` 时，调用 `rehash(0)` 会释放底层桶数组的内存。
	Throws:;; The function has no effect if an exception is thrown, unless it is thrown by the table's hash function or comparison function. Concurrency:;; Blocking on `*this`. ---	抛出异常：;; 若抛出异常，函数不会产生任何效果（由容器的哈希函数或比较函数抛出的异常除外）。并发特性：;; 阻塞当前容器 `*this`。
	reserve	保留
	```c++ void reserve(size_type n); ```	```c++ void reserve(size_type n); ```
	Equivalent to `a.rehash(ceil(n / a.max_load_factor()))`.	效果：;; 等价于 `a.rehash(ceil(n / a.max_load_factor()))`。
	Similar to `rehash`, this function can be used to grow or shrink the number of buckets in the table.	效果：;; 与 `rehash` 功能类似，该函数可用于增大或缩小容器的桶数量。
	Throws:;; The function has no effect if an exception is thrown, unless it is thrown by the table's hash function or comparison function. Concurrency:;; Blocking on `*this`.	抛出异常：;; 若抛出异常，函数不会产生任何效果（由容器的哈希函数或比较函数抛出的异常除外）。并发特性：;; 阻塞当前容器 `*this`。

	Statistics	统计信息
	get_stats	get_stats
	```c++ stats get_stats() const; ```	```c++ stats get_stats() const; ```
	Returns:;; A statistical description of the insertion and lookup operations performed by the table so far. Notes:;; Only available if xref:reference/stats.adoc#stats[statistics calculation] is xref:concurrent_node_map_boost_unordered_enable_stats[enabled].	返回值：;; 表截至目前执行的插入和查找操作的统计信息描述。注意：;; 仅当启用了统计信息计算功能时可用。
:1804	---	---
	reset_stats	reset_stats
	```c++ void reset_stats() noexcept; ```	```c++ void reset_stats() noexcept; ```
	Effects:;; Sets to zero the internal statistics kept by the table. Notes:;; Only available if xref:reference/stats.adoc#stats[statistics calculation] is xref:concurrent_node_map_boost_unordered_enable_stats[enabled].	效果：;; 将容器维护的内部统计数据归零。注意：;; 仅当 xref:reference/stats.adoc#stats[statistics calculation] 被 xref:concurrent_node_map_boost_unordered_enable_stats[enabled] 启用时可用。

	Deduction Guides	推导指引
	A deduction guide will not participate in overload resolution if any of the following are true:	如果以下任何一条件为真，则推导指引将不参与重载决议：
	- It has an `InputIterator` template parameter and a type that does not qualify as an input iterator is deduced for that parameter. - It has an `Allocator` template parameter and a type that does not qualify as an allocator is deduced for that parameter. - It has a `Hash` template parameter and an integral type or a type that qualifies as an allocator is deduced for that parameter. - It has a `Pred` template parameter and a type that qualifies as an allocator is deduced for that parameter.	- 该推导指引包含 `InputIterator` 模板参数，且为此参数推导出的类型不符合输入迭代器的要求。 - 该推导指引包含 `Allocator` 模板参数，且为该参数推导出的类型不符合分配器要求。 - 该推导指引包含 `Hash` 模板参数，且为该参数推导出的类型为整型或符合分配器要求。 - 该推导指引包含 `Pred` 模板参数，且为该参数推导出的类型符合分配器要求。
	A `size_type` parameter type in a deduction guide refers to the `size_type` member type of the table type deduced by the deduction guide. Its default value coincides with the default value of the constructor selected.	推导指引中的 `size++_++type` 参数类型，指向由该推导指引所推导容器类型的 `size++_++type` 成员类型。其默认值与所选构造函数的默认值一致。

	```c++ void reset_stats() noexcept; ```	```c++ void reset_stats() noexcept; ```
	Move construction from a xref:#unordered_node_map[`unordered_node_map`]. The internal bucket array of `other` is transferred directly to the new container. The hash function, predicate and allocator are moved-constructed from `other`. If statistics are xref:concurrent_node_map_boost_unordered_enable_stats[enabled], transfers the internal statistical information from `other` and calls `other.reset_stats()`.	通过 xref:#unordered_node_map[`unordered_node_map`] 进行移动构造。将 `other` 的内部桶数组直接转移到新容器中。哈希函数、谓词和分配器均从 `other` 移动构造而来。若启用了 xref:concurrent_node_map_boost_unordered_enable_stats[统计功能]，则从 `other` 转移内部统计信息，并调用 `other.reset_stats()`。

	Returns `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).	若 `x.size() == y.size()`，且对于 `x` 中的每个元素，`y` 中均存在一个键相同、值相等（使用 `operator==` 比较值类型）的元素，则返回 `true`。
	operator!	operator!
	Returns `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).	若`x.size() == y.size()`，且`x`中每个元素在`y`中都存在键相同、值相等（使用`operator==`比较值类型）的对应元素，则返回`false`。
