:593	Requires:;; `hasher` and `key_equal` need to be https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[DefaultConstructible^].	要求：`hasher` 和 `key_equal` 需满足 https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[可默认构造^] 要求。
:595	---	---
	initializer_list Constructor with Bucket Count and Hasher and Allocator	带桶数、哈希函数和分配器的初始化列表构造函数
	```c++ unordered_flat_map(std::initializer_list<value_type> il, size_type n, const hasher& hf, const allocator_type& a); ```	```c++ unordered_flat_map(std::initializer_list<value_type> il, size_type n, const hasher& hf, const allocator_type& a); ```</value_type>
	Constructs an empty container 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，使用 `hf` 作为哈希函数、`a` 作为分配器以及默认的键相等谓词，并将 `il` 中的元素插入其中。
:607	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。

	Destructor	析构函数
	```c++ ~unordered_flat_map(); ```	```c++ ~unordered_flat_map(); ```
	Note:;; The destructor is applied to every element, and all memory is deallocated	注意：析构函数会应用于每个元素，并且所有内存都会被释放。

	Assignment	赋值操作
	Copy Assignment	复制赋值
	```c++ unordered_flat_map& operator=(unordered_flat_map const& other); ```	```c++ unordered_flat_map& operator=(unordered_flat_map 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`.	赋值操作符。该操作会销毁容器中原有的元素，并从 other 复制赋值哈希函数与键相等性谓词。若 Alloc::propagate_on_container_copy_assignment 存在，且 Alloc::propagate_on_container_copy_assignment::value 为 true，则从 other 复制赋值分配器，最后插入 other 中所有元素的副本。
:635	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/CopyInsertable[CopyInsertable^]	要求：`value_type` 需满足 https://en.cppreference.com/w/cpp/named_req/CopyInsertable[可复制插入^] 要求。
:637	---	---
	Move Assignment	移动赋值
	```c++ unordered_flat_map& operator=(unordered_flat_map&& other) noexcept((boost::allocator_traits<Allocator>::is_always_equal::value \|\| boost::allocator_traits<Allocator>::propagate_on_container_move_assignment::value) && std::is_same<pointer, value_type*>::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 the new container; otherwise, inserts move-constructed copies of the elements of `other`. If statistics are xref:unordered_flat_map_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++ unordered_flat_map& operator=(unordered_flat_map&& other) noexcept((boost::allocator_traits<allocator>::is_always_equal::value \|\| boost::allocator_traits<allocator>::propagate_on_container_move_assignment::value) && std::is_same<pointer, value_type*="">::value); ``` 移动赋值运算符。销毁之前存在的元素，交换 other 中的哈希函数和谓词，若 Alloc::propagate_on_container_move_assignment 存在且 Alloc::propagate_on_container_move_assignment::value 为 true，则从 other 移动赋值分配器。若此时分配器与 other.get_allocator() 相等，则将 other 的内部桶数组直接转移至当前容器；否则，插入通过移动构造从 other 元素创建的副本。若统计功能已启用（参见 xref:unordered_flat_map_boost_unordered_enable_stats[相关说明]），则仅当最终分配器与 other.get_allocator() 相等时转移 other 的内部统计信息，且始终会调用 other.reset_stats()。</pointer,></allocator></allocator>
:654	---	---
	Initializer List Assignment	初始化列表赋值
	```c++ unordered_flat_map& operator=(std::initializer_list<value_type> il); ```	```c++ unordered_flat_map& operator=(std::initializer_list<value_type> il); ```</value_type>
	Assign from values in initializer list. All previously existing elements are destroyed.	从初始化列表中的值进行赋值。所有之前存在的元素均被销毁。
:664	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/CopyInsertable[CopyInsertable^]	要求：`value_type` 需满足 https://en.cppreference.com/w/cpp/named_req/CopyInsertable[可复制插入^] 要求。
	Iterators	迭代器
	begin	begin
	```c++ iterator begin() noexcept; const_iterator begin() const noexcept; ```	```c++ iterator begin() noexcept; const_iterator begin() const noexcept; ```
	Returns:;; An iterator referring to the first element of the container, or if the container is empty the past-the-end value for the container. Complexity:;; O(`bucket_count()`)	返回：指向容器第一个元素的迭代器，若容器为空则返回容器尾后迭代器。复杂度：O(`bucket_count()`)

:757	Requires:;; `value_type` is constructible from `args`. Returns:;; The `bool` component of the return type is `true` if an insert took place. + + If an insert 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:;; Can invalidate iterators, pointers and references, but only if the insert causes the load to be greater than the maximum load. + + If `args...` is of the form `k,v`, it delays constructing the whole object until it is certain that an element should be inserted, using only the `k` argument to check.	要求：`value_type` 可从 `args` 构造。返回：若执行了插入，则返回类型中的 `bool` 分量为 `true`。+ +若执行了插入，则迭代器指向新插入的元素；否则指向等价的元素。抛出：若调用 `hasher` 以外的操作抛出异常，则函数无效果。注意：可能使迭代器、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。+ +若 `args...` 的形式为 `k,v`，则仅在确定应插入元素时才构造整个对象，检查时仅使用 `k` 参数。
