	```c++ void max_load_factor(float z); ```	```c++ void max_load_factor(float z); ```
	Effects:;; Does nothing, as the user is not allowed to change this parameter. Kept for compatibility with `boost::unordered_map`.	效果：无任何操作，用户不允许修改此参数。保留该函数是为了与 `boost::unordered_map` 保持兼容。
:1625	---	---
	max_load	max_load（最大负载）
	```c++ size_type max_load() const noexcept; ```	```c++ size_type max_load() const noexcept; ```
	Returns:;; The maximum number of elements the table can hold without rehashing, assuming that no further elements will be erased. Note:;; After construction, rehash or clearance, the table's maximum load is at least `max_load_factor() * bucket_count()`. This number may decrease on erasure under high-load conditions. + + In the presence of concurrent insertion operations, the value returned may not accurately reflect the true state of the table right after execution.	返回值：容器在不进行重哈希的前提下可容纳的最大元素数量（假定不会再擦除任何元素）。说明：容器在构造、重哈希或清空后，其最大负载量至少为 `max_load_factor() * bucket_count()`。在高负载条件下执行擦除操作时，该数值可能会降低。若存在并发插入操作，返回值可能无法精确反映容器执行后的真实状态。
:1642	---	---
	rehash	重哈希
	```c++ void rehash(size_type n); ```	```c++ void rehash(size_type n); ```
	Changes if necessary the size of the bucket array so that there are at least `n` buckets, and so that the load factor is less than or equal to the maximum load factor. When applicable, this will either grow or shrink the `bucket_count()` associated with the table.	效果：必要时调整桶数组的大小，使桶数量至少为 `n`，且负载因子小于等于最大负载因子。适用场景下，该操作会增大或缩小容器的桶数量 `bucket_count()`。
	When `size() == 0`, `rehash(0)` will deallocate the underlying buckets array.	当容器大小 `size() == 0` 时，调用 `rehash(0)` 会释放底层的桶数组内存。
:1653	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`。
	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`。
:1675	---	---
	Statistics	统计信息
	get_stats	get_stats
	```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。
:1688	---	---
	reset_stats	reset_stats
	```c++ void reset_stats() noexcept; ```	```c++ void reset_stats() noexcept; ```
	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。

	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`。
