Boost Unordered Translation (zh_Hans)/Doc / Modules / Root / Pages / Reference / Unordered Flat Set (adoc) — Chinese (Simplified Han script)
- `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` 必须可移动构造。
- 在重哈希过程中不保持指针稳定性。
- `begin()` 不是常数时间操作。
- 没有用于桶操作的 API（除了 `bucket_count`），也没有节点提取/插入的 API。
- 容器的最大负载因子由内部管理，用户无法设置。

If `link:../../../../../container_hash/doc/html/hash.html#ref_hash_is_avalanchinghash[hash_is_avalanching]<Hash>::value` is `true`, the hash function is used as-is; otherwise, a bit-mixing post-processing stage is added to increase the quality of hashing at the expense of extra computational cost.
如果`link:../../../../../container_hash/doc/html/hash.html#ref_hash_is_avalanching[hash_is_avalanching]<hash>::value` 为 `true`，则哈希函数将按原样使用；否则，将添加一个比特混合后处理阶段，以增加哈希质量，但会增加额外的计算成本。</hash>

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&amp; operator=(unordered_flat_set&amp;&amp; other) noexcept((boost::allocator_traits<allocator>::is_always_equal::value || boost::allocator_traits<allocator>::propagate_on_container_move_assignment::value) &amp;&amp; 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>

Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/MoveInsertable[MoveInsertable^].

返回：;; 如果进行了插入，则返回类型的 `bool` 分量为 `true`。
如果进行了插入，则迭代器指向新插入的元素；否则，指向具有等价键的元素。
抛出：;; 如果除调用 `hasher` 之外的操作抛出异常，则该函数无效。

Inserts an element constructed from `std::forward<K>(k)` in the container if and only if there is no element in the container with an equivalent key.
当且仅当容器中不存在具有等价键的元素时，才插入一个从 `std::forward<k>(k)` 构造的元素。</k>

Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[EmplaceConstructible^] into the container from `*first`. Throws:;; When inserting a single element, if an exception is thrown by an operation other than a call to `hasher` the function has no effect.

Returns:;; The number of elements erased. Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`. Notes:;; The `template<class K>` overload only participates in overload resolution if `Hash::is_transparent` and `Pred::is_transparent` are valid member typedefs and neither `iterator` nor `const_iterator` are implicitly convertible from `K`. The library assumes that `Hash` is callable with both `K` and `Key` and that `Pred` is transparent. This enables heterogeneous lookup which avoids the cost of instantiating an instance of the `Key` type.
返回：;; 被删除的元素数量。抛出：;; 仅当由 `hasher` 或 `key_equal` 抛出异常时才会抛出异常。备注：;; `template<class k="">` 重载仅当 `Hash::is_transparent` 和 `Pred::is_transparent` 是有效的成员 typedef，并且 `K` 不能隐式转换为 `iterator` 或 `const_iterator` 时，才会参与重载决议。库假定 `Hash` 可同时以 `K` 和 `Key` 类型调用，且 `Pred` 是透明的。这支持了异构查找，从而避免了实例化 `Key` 类型的开销。</class>
