	Constructs an empty table with at least `n` buckets, using `hf` as the hash function, `a` as the allocator and default key equality predicate,and inserts the elements from `il` into it.	构造一个至少包含 `n` 个桶的空容器，以 `hf` 作为哈希函数、`a` 作为分配器，使用默认键相等谓词，并将 `il` 中的元素插入其中。
:649	Requires:;; `key_equal` needs to be https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[DefaultConstructible^].	要求：`key_equal` 需满足 https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[可默认构造^] 要求。
:651	---	---
	Destructor	析构函数
	```c++ ~concurrent_flat_set(); ```	```c++ ~concurrent_flat_set(); ```
	Note:;; The destructor is applied to every element, and all memory is deallocated	注意：;; 析构函数会作用于所有元素，且所有内存都会被释放
:662	---	---
	Assignment	赋值操作
	Copy Assignment	复制赋值
	```c++ concurrent_flat_set& operator=(concurrent_flat_set const& other); ```	```c++ concurrent_flat_set& operator=(concurrent_flat_set const& other); ```
	The assignment operator. Destroys previously existing elements, copy-assigns the hash function and predicate from `other`, copy-assigns the allocator from `other` if `Alloc::propagate_on_container_copy_assignment` exists and `Alloc::propagate_on_container_copy_assignment::value` is `true`, and finally inserts copies of the elements of `other`.	赋值运算符。销毁先前已存在的元素，从 `other` 拷贝赋值哈希函数和谓词；若 `Alloc::propagate_on_container_copy_assignment` 存在且其值为 `true`，则从 `other` 拷贝赋值分配器；最后插入 `other` 元素的副本。
	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/CopyInsertable[CopyInsertable^] Concurrency:;; Blocking on `*this` and `other`.	要求：`value_type` 需满足 https://en.cppreference.com/w/cpp/named_req/CopyInsertable[可复制插入^] 要求。并发：阻塞 `*this` 和 `other`。
:680	---	---
	Move Assignment	移动赋值
	```c++ concurrent_flat_set& operator=(concurrent_flat_set&& other) noexcept(boost::allocator_traits<Allocator>::is_always_equal::value \|\| boost::allocator_traits<Allocator>::propagate_on_container_move_assignment::value); ``` The move assignment operator. Destroys previously existing elements, swaps the hash function and predicate from `other`, and move-assigns the allocator from `other` if `Alloc::propagate_on_container_move_assignment` exists and `Alloc::propagate_on_container_move_assignment::value` is `true`. If at this point the allocator is equal to `other.get_allocator()`, the internal bucket array of `other` is transferred directly to `*this`; otherwise, inserts move-constructed copies of the elements of `other`. If statistics are xref:concurrent_flat_set_boost_unordered_enable_stats[enabled], transfers the internal statistical information from `other` iff the final allocator is equal to `other.get_allocator()`, and always calls `other.reset_stats()`.	```c++ concurrent_flat_set& operator=(concurrent_flat_set&& other) noexcept(boost::allocator_traits<allocator>::is_always_equal::value \|\| boost::allocator_traits<allocator>::propagate_on_container_move_assignment::value); ``` 移动赋值运算符。销毁先前已存在的元素，交换当前对象与 other 的哈希函数和谓词；若 Alloc::propagate_on_container_move_assignment 存在且其值为 true，则从 other 移动赋值分配器。若此时分配器与 other.get_allocator() 相等，other 的内部桶数组将直接转移给 *this；否则，插入由 other 元素移动构造的副本。若统计功能已通过 xref:concurrent_flat_set_boost_unordered_enable_stats [enabled]，仅当最终分配器与 other.get_allocator() 相等时，从 other 转移内部统计信息，且始终调用 other.reset_stats()。</allocator></allocator>
	Concurrency:;; Blocking on `*this` and `other`.	并发特性：;; 阻塞 `*this` 与 `other`
:699	---	---
	Initializer List Assignment	初始化列表赋值
	```c++ concurrent_flat_set& operator=(std::initializer_list<value_type> il); ```	```c++ concurrent_flat_set& operator=(std::initializer_list<value_type> il); ```</value_type>
	Assign from values in initializer list. All previously existing elements are destroyed.	通过初始化列表中的值进行赋值。先前存在的所有元素都会被销毁。
	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/CopyInsertable[CopyInsertable^] Concurrency:;; Blocking on `*this`.	前置要求：;; `value_type` 需满足 https://en.cppreference.com/w/cpp/named_req/CopyInsertable[CopyInsertable^] 并发特性：;; 阻塞 `*this`

	If an element `x` exists with key equivalent to `k`, invokes `f` with a const reference to `x`.	若存在键与 `k` 等价的元素 `x`，则以指向 `x` 的常量引用调用函数 `f`。
	Returns:;; The number of elements visited (0 or 1). Notes:;; The `template<class K, class F>` 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.	返回值：;; 访问到的元素数量（0 或 1）。注意：;; 仅当 `Hash::is_transparent` 与 `Pred::is_transparent` 为合法成员别名时，`template<class k,="" class="" f="">` 重载版本才会参与重载决议。库假定 `Hash` 可同时接收 `K` 与 `Key` 类型调用，且 `Pred` 是透明的。这支持异构查找，避免了实例化 `Key` 类型对象的开销。</class>

	Bulk visit	批量访问
	```c++ template<class FwdIterator, class F> size_t visit(FwdIterator first, FwdIterator last, F f); template<class FwdIterator, class F> size_t visit(FwdIterator first, FwdIterator last, F f) const; template<class FwdIterator, class F> size_t cvisit(FwdIterator first, FwdIterator last, F f) const; ```	```c++ template<class fwditerator,="" class="" f=""> size_t visit(FwdIterator first, FwdIterator last, F f); template<class fwditerator,="" class="" f=""> size_t visit(FwdIterator first, FwdIterator last, F f) const; template<class fwditerator,="" class="" f=""> size_t cvisit(FwdIterator first, FwdIterator last, F f) const; ```</class></class></class>
	For each element `k` in the range [`first`, `last`), if there is an element `x` in the container with key equivalent to `k`, invokes `f` with a const reference to `x`.	对范围 `[first, last)` 中的每个元素 `k`，若容器中存在键与 `k` 等价的元素 `x`，则以指向 `x` 的常量引用调用函数 `f`。
