	An iterator whose value type is `value_type`.	一种迭代器，其值类型为 `value++_++type` 。
:344	The iterator category is at least a forward iterator.	迭代器类别至少为前向迭代器。
	Convertible to `const_iterator`.	可转换为 `const++_++iterator` 。

	A constant iterator whose value type is `value_type`.	一个常量迭代器，其值类型为 `value++_++type` 。
:357	The iterator category is at least a forward iterator.	迭代器类别至少为前向迭代器。
	Constructors	构造函数
	Default Constructor	默认构造函数
	```c++ unordered_flat_map(); ```	```c++ unordered_flat_map(); ```
	Constructs an empty container using `hasher()` as the hash function, `key_equal()` as the key equality predicate and `allocator_type()` as the allocator.	构造一个空容器，使用 `hasher()` 作为哈希函数、 `key++_++equal()` 作为键相等性谓词、以及 `allocator++_++type()` 作为分配器。
:370	Postconditions:;; `size() == 0` Requires:;; If the defaults are used, `hasher`, `key_equal` and `allocator_type` need to be https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[DefaultConstructible^].	后置条件：`size() == 0` 要求：若使用默认参数，则 `hasher`、`key_equal` 和 `allocator_type` 需满足 https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[可默认构造^] 要求。
:373	---	---
	Bucket Count Constructor	桶数构造函数
	```c++ explicit unordered_flat_map(size_type n, const hasher& hf = hasher(), const key_equal& eql = key_equal(), const allocator_type& a = allocator_type()); ```	```c++ explicit unordered_flat_map(size_type n, const hasher& hf = hasher(), const key_equal& eql = key_equal(), const allocator_type& a = allocator_type()); ```
	Constructs an empty container with at least `n` buckets, using `hf` as the hash function, `eql` as the key equality predicate, and `a` as the allocator.	构造一个至少包含 `n` 个桶的空容器，使用 `hf` 作为哈希函数、 `eql` 作为键相等性谓词、以及 `a` 作为分配器。
:387	Postconditions:;; `size() == 0` Requires:;; If the defaults are used, `hasher`, `key_equal` and `allocator_type` need to be https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[DefaultConstructible^].	后置条件：`size() == 0` 要求：若使用默认参数，则 `hasher`、`key_equal` 和 `allocator_type` 需满足 https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[可默认构造^] 要求。

	Iterator Range Constructor	迭代器范围构造函数
	Constructs an empty container with at least `n` buckets, using `hf` as the hash function, `eql` as the key equality predicate and `a` as the allocator, and inserts the elements from `[f, l)` 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、 `eql` 作为键相等性谓词、 `a` 作为分配器，并将区间 `++[++f, l)` 中的元素插入其中。
:406	Requires:;; If the defaults are used, `hasher`, `key_equal` and `allocator_type` need to be https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[DefaultConstructible^].	要求;; 若使用默认值，则 `hasher` 、 `key++_++equal` 和 `allocator++_++type` 需满足 https://en.cppreference.com/w/cpp/named_req/DefaultConstructible[可默认构造] 要求。
:408	---	---
	Copy Constructor	复制构造函数
	```c++ unordered_flat_map(unordered_flat_map const& other); ```	```c++ unordered_flat_map(unordered_flat_map const& other); ```
	The copy constructor. Copies the contained elements, hash function, predicate and allocator.	复制构造函数。复制所含元素、哈希函数、谓词和分配器。
	If `Allocator::select_on_container_copy_construction` exists and has the right signature, the allocator will be constructed from its result.	若 `Allocator::select++_++on++_++container++_++copy++_++construction` 存在且签名正确，则将根据其结果来构造分配器。
	Requires:;; `value_type` is copy constructible	要求：`value_type` 需满足可复制构造要求。
:422	---	---
	Move Constructor	移动构造函数
	```c++ unordered_flat_map(unordered_flat_map&& other); ```	```c++ unordered_flat_map(unordered_flat_map&& other); ```
	The move constructor. 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()`.	移动构造函数。`other` 的内部桶数组直接转移到新容器中。哈希函数、谓词和分配器通过移动构造从 `other` 获得。若统计功能已启用（参见 xref:unordered_flat_map_boost_unordered_enable_stats[相关说明]），则转移 `other` 的内部统计信息并调用 `other.reset_stats()`。

:1461	---	---
:1473	Notes:;; Behavior is undefined if the two containers don't have equivalent equality predicates.	注意：如果两个容器的相等谓词不等价，则行为未定义。
:1485	If `Allocator::propagate_on_container_swap` is declared and `Allocator::propagate_on_container_swap::value` is `true` then the containers' allocators are swapped. Otherwise, swapping with unequal allocators results in undefined behavior.	如果 `Allocator::propagate_on_container_swap` 已声明且 `Allocator::propagate_on_container_swap::value` 为 `true`，则交换容器的分配器。否则，使用不相等的分配器进行交换将导致未定义行为。

:324	---	若 link:../../../../../container_hash/doc/html/hash.html#ref_hash_is_avalanchinghash[`hash++_++is++_++avalanching`]`++<++Hash++>++::value` 为 `true` ，则直接使用哈希函数；否则，会添加一个位混合后处理阶段以提高哈希质量，但会牺牲额外的计算成本。
