	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：;; 若抛出异常，函数无任何效果（哈希函数或比较函数抛出的异常除外）。并发：;; 阻塞`*this`。 ---
	reserve	保留

	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 container 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。

	Equality Comparisons	相等性比较
	operator	operator
	```c++ template<class Key, class Hash, class Pred, class Alloc> bool operator==(const concurrent_flat_set<Key, Hash, Pred, Alloc>& x, const concurrent_flat_set<Key, Hash, Pred, Alloc>& y); ```	```c++ template<class key,="" class="" hash,="" pred,="" alloc=""> bool operator==(const concurrent_flat_set<key, hash,="" pred,="" alloc="">& x, const concurrent_flat_set<key, hash,="" pred,="" alloc="">& y); ```</key,></key,></class>
	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 中均存在一个具有相同键、值相等（使用 operator== 比较值类型）的元素，则返回 true。
:1532	Concurrency:;; Blocking on `x` and `y`. Notes:;; Behavior is undefined if the two tables don't have equivalent equality predicates.	并发：;; 对`x`和`y`进行阻塞。备注：;; 若两个哈希表的相等判断谓词不一致，行为未定义。

	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()，且对于 x 中的每个元素，y 中均存在一个具有相同键、值相等（使用 operator== 比较值类型）的元素，则返回 false。

	```c++ bool contains(const key_type& k) const; template<class K> bool contains(const K& k) const; ```	```c++ bool contains(const key_type& k) const; template<class k=""> bool contains(const K& k) const; ```</class>
	Returns:;; A boolean indicating whether or not there is an element with key equal to `k` in the table. Notes:;; The `template<class K>` overload only participates 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. + + In the presence of concurrent insertion operations, the value returned may not accurately reflect the true state of the table right after execution.	返回值：;; 布尔值，表示表中是否存在键与`k`相等的元素。备注：;; `template<class k="">` 重载仅当 `Hash::is_transparent` 和 `Pred::is_transparent` 为合法成员类型别名时才参与重载决议。标准库假定 `Hash` 可同时接受 `K` 与 `Key` 类型调用，且 `Pred` 是透明的。这实现了异构查找，避免了实例化 `Key` 类型对象的开销。在存在并发插入操作时，返回的值可能无法准确反映执行后表的真实状态。</class>

	max_load_factor	max_load_factor
	max_load	max_load（最大负载）
	```c++ size_type max_load() const noexcept; ```	```c++ size_type max_load() const noexcept; ```
	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：;; 必要时调整哈希桶数组的大小，使桶数量至少为 `n`，且负载因子小于等于最大负载因子。适用情况下，该操作会增大或缩小哈希表的桶数量（`bucket_count()`）。
	When `size() == 0`, `rehash(0)` will deallocate the underlying buckets array.	当 `size() == 0` 时，`rehash(0)` 会释放底层的哈希桶数组内存。
	Similar to `rehash`, this function can be used to grow or shrink the number of buckets in the table.	与 `rehash` 功能类似，该函数可用于增加或减少哈希表中的桶数量。
	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：;; 若抛出异常，函数不会产生任何效果（哈希表的哈希函数或比较函数抛出的异常除外）。并发：;; 阻塞`*this`。
	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_flat_set_boost_unordered_enable_stats[enabled].	效果：;; 将哈希表内部统计数据置零。备注：;; 仅当 xref:reference/stats.adoc#stats[统计计算] 被 xref:concurrent_flat_set_boost_unordered_enable_stats[启用] 时，本接口方可使用。
