	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 container can hold without rehashing, assuming that no further elements will be erased. Note:;; After construction, rehash or clearance, the container's maximum load is at least `max_load_factor() * bucket_count()`. This number may decrease on erasure under high-load conditions.	返回：;; 假设不再删除更多元素，容器在不进行重哈希的情况下所能容纳的最大元素数量。注意：;; 在构造、重哈希或清空之后，容器的最大负载至少为 `max_load_factor() * bucket_count()`。在高负载条件下，该值可能因删除操作而减小。
:1118	---	---
	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 container.	必要时改变桶数组的大小，使得至少包含 `n` 个桶，并且负载因子小于或等于最大负载因子。在适用的情况下，这将增大或缩小与容器相关联的 `bucket_count()`。
	When `size() == 0`, `rehash(0)` will deallocate the underlying buckets array. If the provided Allocator uses fancy pointers, a default allocation is subsequently performed.	当 `size() == 0` 时，`rehash(0)` 将释放底层桶数组的内存。如果所提供的分配器使用 fancy pointers，随后将执行一次默认分配。
:1129	Invalidates iterators, pointers and references, and changes the order of elements.	使迭代器、指针和引用失效，并改变元素的顺序。
:1132	Throws:;; The function has no effect if an exception is thrown, unless it is thrown by the container's hash function or comparison function.	抛出：;; 如果抛出异常（除非是由容器的哈希函数或比较函数抛出），则该函数无效。
:1134	---	---
	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 container.	与 `rehash` 类似，此函数可用于增加或减少容器中桶的数量。

	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`.	赋值运算符。销毁先前存在的元素，从 `other` 复制赋值哈希函数和谓词，如果 `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` 元素的副本。

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_set_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_set& operator=(unordered_flat_set&& 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。销毁先前存在的元素，交换来自 `other` 的哈希函数和谓词，如果 `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。如果此时分配器等于 `other.get_allocator()`，则 `other` 的内部桶数组直接转移给当前容器；否则，插入 `other` 元素的移动构造副本。如果启用了统计信息（xref:unordered_flat_set_boost_unordered_enable_stats[enabled]），则仅当最终的分配器等于 `other.get_allocator()` 时才从 `other` 转移内部统计信息，并且总是调用 `other.reset_stats()`。</pointer,></allocator></allocator>
