	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。

	English	Chinese (Simplified Han script)	Actions
	```c++ iterator insert(const_iterator hint, const value_type& obj); iterator insert(const_iterator hint, const init_type& obj); ``` Inserts `obj` in the container if and only if there is no element in the container with an equivalent key.	`iterator insert(const_iterator hint, const value_type& obj); iterator insert(const_iterator hint, const init_type& obj);` 当且仅当容器中没有等价的键时，将 `obj` 插入容器。
	- `value_type` must be move-constructible. - Pointer stability is not kept under rehashing. - `begin()` is not constant-time. - There is no API for bucket handling (except `bucket_count`) or node extraction/insertion. - The maximum load factor of the container is managed internally and can't be set by the user.	- `value++_++type` 必须支持移动构造。 - 在重哈希的过程中，指针稳定性无法保持。 - `begin()` 不是常数时间复杂度操作。 - 未提供用于桶管理（除 `bucket++_++count` 外）或节点提取/插入的 API。 - 容器的最大负载因子由内部管理，用户无法进行设置。
	The elements of the container are held into an internal _bucket array_. An element is inserted into a bucket determined by its hash code, but if the bucket is already occupied (a _collision_), an available one in the vicinity of the original position is used.	容器的元素存储在内部的__桶数组__中。元素根据其哈希码被插入到对应的桶中，但如果该桶已被占用（即发生__冲突__），则会使用原始位置附近可用的桶。
	Erase by Position	通过位置擦除
	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/CopyInsertable[CopyInsertable^]. 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. + + A call of the form `insert(hint, x)`, where `x` is equally convertible to both `const value_type&` and `const init_type&`, is not ambiguous and selects the `init_type` overload.	要求：`value_type` 需满足 https://en.cppreference.com/w/cpp/named_req/CopyInsertable[可复制插入^] 要求。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。+ +形式为 `insert(hint, x)` 的调用（其中 `x` 可同等转换为 `const value_type&` 和 `const init_type&`）不会产生歧义，并且会选择 `init_type` 重载。
	Erase the element pointed to by `position`.	擦除由 `position` 指向的元素。
	Erase by Key	通过键擦除
	The size of the bucket array can be automatically increased by a call to `insert`/`emplace`, or as a result of calling `rehash`/`reserve`. The _load factor_ of the container (number of elements divided by number of buckets) is never greater than `max_load_factor()`, except possibly for small sizes where the implementation may decide to allow for higher loads.	桶数组的大小可通过调用 `insert` / `emplace` 自动增加，也可通过调用 `rehash` / `reserve` 来调整。容器的__负载因子__（元素数量与桶数量的比值）始终不会超过 `max++_++load++_++factor()` ，但在小规模数据情况下，实现可能允许更高的负载因子。
	Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/MoveInsertable[MoveInsertable^]. 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. + + A call of the form `insert(hint, x)`, where `x` is equally convertible to both `value_type&&` and `init_type&&`, is not ambiguous and selects the `init_type` overload.	要求：`value_type` 需满足 https://en.cppreference.com/w/cpp/named_req/MoveInsertable[可移动插入^] 要求。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。+ +形式为 `insert(hint, x)` 的调用（其中 `x` 可同等转换为 `value_type&&` 和 `init_type&&`）不会产生歧义，并且会选择 `init_type` 重载。
	If `a == other.get_allocator()`, the elements of `other` are transferred directly to the new container; otherwise, elements are moved-constructed from those of `other`. The hash function and predicate are moved-constructed from `other`, and the allocator is copy-constructed from `a`. If statistics are xref:unordered_flat_map_boost_unordered_enable_stats[enabled], transfers the internal statistical information from `other` iff `a == other.get_allocator()`, and always calls `other.reset_stats()`.	若 `a == other.get_allocator()`，则 `other` 的元素直接转移到新容器中；否则，将通过移动构造从 `other` 的元素创建新元素。哈希函数和谓词通过移动构造从 `other` 获得，分配器则通过复制构造从 `a` 获得。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 `a == other.get_allocator()` 时转移 `other` 的内部统计信息，且始终会调用 `other.reset_stats()`。
	Move construction from a xref:#concurrent_flat_map[`concurrent_flat_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:unordered_flat_map_boost_unordered_enable_stats[enabled], transfers the internal statistical information from `other` and calls `other.reset_stats()`.	从 xref:#concurrent_flat_map[`concurrent_flat_map`][`concurrent++_++flat++_++map`] 移动构造。 `other` 的内部桶数组直接转移至新容器。哈希函数、谓词和分配器均从 `other` 移动构造。若统计功能 xref:#unordered_flat_map_boost_unordered_enable_stats[已启用] ，则转移 `other` 的内部统计信息，并调用 `other.reset++_++stats()` 。
	Erases the elements in the range from `first` to `last`.	擦除从 `first` 到 `last` 范围内的元素。
	Returns:;; The iterator following the erased elements - i.e. `last`. Throws:;; Nothing in this implementation (neither the `hasher` nor the `key_equal` objects are called).	返回：指向被擦除元素之后位置的迭代器，即 `last`。抛出：在此实现中不会抛出异常（既不调用 `hasher` 也不调用 `key_equal` 对象）。
	swap	交换
	Iterator Range Constructor with Bucket Count and Hasher	带桶数和哈希函数的迭代器范围构造函数
	Constructs an empty container using `a` and default hash function and key equality predicate, and inserts the elements from `il` into it.	构造一个空容器，使用 `a` 作为分配器、以及默认的哈希函数和键相等性谓词，并将 `il` 中的元素插入其中。
	Destructor	析构函数
	```c++ ~unordered_flat_map(); ```	```c++ ~unordered_flat_map(); ```
	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。
	```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>
	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。
	Throws:;; Nothing unless `key_equal` or `hasher` throw on swapping.	抛出：除非 `key_equal` 或 `hasher` 在交换时抛出异常，否则不会抛出异常。
	pull	pull
	```c++ init_type pull(const_iterator position); ```	```c++ init_type pull(const_iterator position); ```
	```c++ template<class... Args> std::pair<iterator, bool> try_emplace(const key_type& k, Args&&... args); template<class... Args> std::pair<iterator, bool> try_emplace(key_type&& k, Args&&... args); template<class K, class... Args> std::pair<iterator, bool> try_emplace(K&& k, Args&&... args); ```	```c++ template<class... args=""> std::pair<iterator, bool=""> try_emplace(const key_type& k, Args&&... args); template<class... args=""> std::pair<iterator, bool=""> try_emplace(key_type&& k, Args&&... args); template<class k,="" class...="" args=""> std::pair<iterator, bool=""> try_emplace(K&& k, Args&&... args); ```</iterator,></class></iterator,></class...></iterator,></class...>
	begin	begin
	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` 对象 `x`，擦除该元素并返回 `x`。
	```c++ iterator begin() noexcept; const_iterator begin() const noexcept; ```	```c++ iterator begin() noexcept; const_iterator begin() const noexcept; ```
