	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 container.	必要时改变桶数组的大小，使得至少包含 `n` 个桶，并且负载因子小于或等于最大负载因子。在适用的情况下，这将增大或缩小与容器相关联的 `bucket_count()`。
	When `size() == 0`, `rehash(0)` will deallocate the underlying buckets array. If the provided Allocator uses fancy pointers, a default allocation is subsequently performed.	当 `size() == 0` 时，`rehash(0)` 将释放底层桶数组的内存。如果所提供的分配器使用 fancy pointers，随后将执行一次默认分配。
:1129	Invalidates iterators, pointers and references, and changes the order of elements.	使迭代器、指针和引用失效，并改变元素的顺序。
:1132	Throws:;; The function has no effect if an exception is thrown, unless it is thrown by the container's hash function or comparison function.	抛出：;; 如果抛出异常（除非是由容器的哈希函数或比较函数抛出），则该函数无效。

	Equivalent to `a.rehash(ceil(n / a.max_load_factor()))`.	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 container.	与 `rehash` 类似，此函数可用于增加或减少容器中桶的数量。

	Deduction Guides	推导指引
	A deduction guide will not participate in overload resolution if any of the following are true:	在以下任一条件成立时，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.	- 它具有 `InputIterator` 模板参数，并且为该参数推导出的类型不符合输入迭代器的要求。- 它具有 `Allocator` 模板参数，并且为该参数推导出的类型不符合分配器的要求。- 它具有 `Hash` 模板参数，并且为该参数推导出的是整数类型或符合分配器要求的类型。- 它具有 `Pred` 模板参数，并且为该参数推导出的是符合分配器要求的类型。
	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出的容器类型的 `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 T, class Hash, class Pred, class Alloc> bool operator==(const unordered_flat_set<Key, T, Hash, Pred, Alloc>& x, const unordered_flat_set<Key, T, Hash, Pred, Alloc>& y); ```	```c++ template<class key,="" class="" t,="" hash,="" pred,="" alloc=""> bool operator==(const unordered_flat_set<key, t,="" hash,="" pred,="" alloc="">& x, const unordered_flat_set<key, t,="" 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()` 并且对于 `x` 中的每个元素，在 `y` 中都有一个具有相同键且值相等的元素（使用 `operator==` 比较值类型），则返回 `true`。
:1208	Notes:;; Behavior is undefined if the two containers don't have equivalent equality predicates.	备注：;; 如果两个容器不具有等价的相等谓词，则行为未定义。

	English	Chinese (Simplified Han script)	Actions
	Constructs an empty container using `a` and default hash function and key equality predicate, and inserts the elements from `il` into it.	使用 `a` 以及默认的哈希函数和键相等谓词构造一个空容器，并将 `il` 中的元素插入其中。
	Copy Insert with Hint	带提示的复制插入
	```c++ iterator insert(const_iterator hint, const value_type& obj); ``` Inserts `obj` in the container if and only if there is no element in the container with an equivalent key.	```c++iterator insert(const_iterator hint, const value_type& obj); ```当且仅当容器中不存在具有等价键的元素时，才将 `obj` 插入容器中。
	Transparent Insert with Hint	带提示的透明插入
	```c++ template<class K> std::pair<iterator, bool> insert(const_iterator hint, K&& k); ```	```c++ template<class k=""> std::pair<iterator, bool=""> insert(const_iterator hint, K&& k); ```</iterator,></class>
	Effects:;; Sets to zero the internal statistics kept by the container. Notes:;; Only available if xref:reference/stats.adoc#stats[statistics calculation] is xref:unordered_flat_set_boost_unordered_enable_stats[enabled].	效果：;; 将容器内部保持的统计信息归零。备注：;; 仅在 xref:reference/stats.adoc#stats[统计信息计算] 已 xref:unordered_flat_set_boost_unordered_enable_stats[启用] 时可用。
	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, pointers and references, but only if the insert causes the load to be greater than the maximum load.	要求：;; `value_type` 可以从 `*first` 进行 https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[EmplaceConstructible^] 到容器中。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。备注：;; 可能会使迭代器、指针和引用失效，但仅当插入导致负载大于最大负载时才会发生。
	```c++ iterator erase(const_iterator first, const_iterator last); ```	```c++ iterator erase(const_iterator first, const_iterator last); ```

	```c++ init_type pull(const_iterator position); ```	```c++ init_type pull(const_iterator position); ```
	Move-constructs an `init_value` `x` from the element pointed to by `position`, erases the element and returns `x`.	从 `position` 指向的元素移动构造一个 `init_value` `x`，删除该元素并返回 `x`。
	```c++ template<class H2, class P2> void merge(unordered_flat_set<Key, T, H2, P2, Allocator>& source); template<class H2, class P2> void merge(unordered_flat_set<Key, T, H2, P2, Allocator>&& source); ```	```c++ template<class h2,="" class="" p2=""> void merge(unordered_flat_set<key, t,="" h2,="" p2,="" allocator="">& source); template<class h2,="" class="" p2=""> void merge(unordered_flat_set<key, t,="" h2,="" p2,="" allocator="">&& source); ```</key,></class></key,></class>
	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：;; 一个范围，包含所有键与 `k` 等价的元素。若容器中不包含任何此类元素，则返回 `std::make_pair(b.end(), b.end())`。备注：;; `template<class k="">` 重载仅当 `Hash::is_transparent` 和 `Pred::is_transparent` 是有效的成员 typedef 时才会参与重载决议。库假定 `Hash` 可同时以 `K` 和 `Key` 类型调用，且 `Pred` 是透明的。这支持了异构查找，从而避免了实例化 `Key` 类型的开销。</class>
	Equivalent to `a.rehash(ceil(n / a.max_load_factor()))`.	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 container.	与 `rehash` 类似，此函数可用于增加或减少容器中桶的数量。
