	Throws:;; The function has no effect if an exception is thrown, unless it is thrown by the table's hash function or comparison function. Concurrency:;; Blocking on `*this`. ---	异常：若抛出异常，函数无任何效果（由容器的哈希函数或比较函数抛出的异常除外）。并发：阻塞当前对象 `*this`。
	reserve	保留
	```c++ void reserve(size_type n); ```	```c++ void reserve(size_type n); ```
	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 table.	与 `rehash` 功能类似，该函数可用于增大或缩小容器的桶数量。
:1669	Invalidates pointers and references to elements, and changes the order of elements.	会使指向元素的指针和引用失效，并改变元素的存储顺序。
	Throws:;; The function has no effect if an exception is thrown, unless it is thrown by the table's hash function or comparison function. Concurrency:;; Blocking on `*this`.	异常：若抛出异常，函数无任何效果（由容器的哈希函数或比较函数抛出的异常除外）。并发：阻塞当前对象 `*this`。

	```c++ stats get_stats() const; ```	```c++ stats get_stats() const; ```
	Returns:;; A statistical description of the insertion and lookup operations performed by the table so far. Notes:;; Only available if xref:reference/stats.adoc#stats[statistics calculation] is xref:concurrent_flat_map_boost_unordered_enable_stats[enabled].	返回值：容器截至目前执行的插入与查找操作的统计描述信息。说明：仅当启用统计计算时，该函数才可用。

	Effects:;; Sets to zero the internal statistics kept by the table. Notes:;; Only available if xref:reference/stats.adoc#stats[statistics calculation] is xref:concurrent_flat_map_boost_unordered_enable_stats[enabled].	效果：将容器维护的内部统计数据归零。说明：仅当启用统计计算时，该函数才可用。

	Deduction Guides	推导指引
	A deduction guide will not participate in overload resolution if any of the following are true:	满足以下任一条件时，推导指引不参与重载决议：
	- 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.	- 该推导指引包含 `InputIterator` 模板参数，且为此参数推导出的类型不符合输入迭代器的要求。 - 该推导指引包含 `Allocator` 模板参数，且为该参数推导出的类型不符合分配器要求。 - 该推导指引包含 `Hash` 模板参数，且为该参数推导出的类型为整型或符合分配器要求。 - 该推导指引包含 `Pred` 模板参数，且为该参数推导出的类型符合分配器要求。
	A `size_type` parameter type in a deduction guide refers to the `size_type` member type of the table 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。

	Returns `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).	若 `x.size() == y.size()`，且对于 `x` 中的每个元素，`y` 中均存在拥有相同键、值相等（使用 `operator==` 比较值类型）的元素，则返回 `true`。
:1758	Concurrency:;; Blocking on `x` and `y`. Notes:;; Behavior is undefined if the two tables don't have equivalent equality predicates.	并发：阻塞 `x` 和 `y`。说明：若两个容器的相等判断谓词不一致，行为未定义。

	`boost::concurrent_flat_map` — A hash table that associates unique keys with another value and allows for concurrent element insertion, erasure, lookup and access without external synchronization mechanisms.	`boost::concurrent_flat_map` — 一种哈希表，将唯一键与对应值关联，并允许在无需外部同步机制的情况下进行并发的元素插入、删除、查找和访问。
	Even though it acts as a container, `boost::concurrent_flat_map` does not model the standard C++ https://en.cppreference.com/w/cpp/named_req/Container[Container^] concept. In particular, iterators and associated operations (`begin`, `end`, etc.) are not provided. Element access and modification are done through user-provided _visitation functions_ that are passed to `concurrent_flat_map` operations where they are executed internally in a controlled fashion. Such visitation-based API allows for low-contention concurrent usage scenarios.	尽管它充当容器的角色，boost::concurrent_flat_map 并未遵循标准 C++ 的 https://en.cppreference.com/w/cpp/named_req/Container[Container^] 概念。特别地，它不提供迭代器及相关操作（例如 begin、end 等）。元素的访问和修改是通过用户提供的访问函数来完成的，这些函数被传递给 concurrent_flat_map 的操作，并以受控的方式在内部执行。这种基于访问的 API 能够实现低竞争并发的使用场景。
	The internal data structure of `boost::concurrent_flat_map` is similar to that of `boost::unordered_flat_map`. As a result of its using open-addressing techniques, `value_type` must be move-constructible and pointer stability is not kept under rehashing.	`boost::concurrent++_++flat++_++map` 的内部数据结构与 `boost::unordered++_++flat++_++map` 类似。由于采用开放寻址技术， `value++_++type` 必须支持移动构造，且在重哈希过程中无法保持指针稳定性。

	Constructs an empty table using `hasher()` as the hash function, `key_equal()` as the key equality predicate and `allocator_type()` as the allocator.	使用hasher()作为哈希函数、key_equal()作为键相等谓词、allocator_type()作为分配器，构造一个空表。
	`std::pair<const Key, T>` must be https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[EmplaceConstructible^] into the table from any `std::pair` object convertible to it, and it also must be https://en.cppreference.com/w/cpp/named_req/Erasable[Erasable^] from the table.	`std::pair<const key,="" t="">` 必须能够从任何可转换为其的 `std::pair` 对象出发，在表中进行 https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[EmplaceConstructible^] 构造，并且也必须可以从表中进行 https://en.cppreference.com/w/cpp/named_req/Erasable[Erasable^] 擦除。</const>
