_Hash_
Boost Unordered Translation (zh_Hans)/Doc / Modules / Root / Pages / Reference / Concurrent Node Set (adoc) — Chinese (Simplified Han script)
A unary function object type that acts a hash function for a `Key`. It takes a single argument of type `Key` and returns a value of type `std::size_t`.
一元函数对象类型，用作 `Key` 的哈希函数。它接受一个类型为 `Key`

`std::allocator_traits<Allocator>::pointer` and `std::allocator_traits<Allocator>::const_pointer` must be convertible to/from `value_type*` and `const value_type*`, respectively.
`std::allocator_traits<allocator>::pointer` 与 `std::allocator_traits<allocator>::const_pointer` 必须分别可与 `value_type*` 和 `const value_type*` 相互转换。</allocator></allocator>

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.
若 `link:../../../../../container_hash/doc/html/hash.html#ref_hash_is_avalanchinghash[hash_is_avalanching]<hash>::value` 为 `true`，则直接使用原哈希函数；否则会添加一个位混合后置处理阶段，以额外计算开销为代价提升哈希质量。</hash>

Boost Unordered Translation (zh_Hans)/Doc / Modules / Root / Pages / Reference / Concurrent Node Set (adoc) — Chinese (Simplified Han script)
If `a == other.get_allocator()`, the elements of `other` are transferred directly to the new table; otherwise, elements are moved-constructed from those of `other`. The hash function and predicate are moved-constructed from `other`, and the allocator is copy-constructed from `a`. If statistics are xref:concurrent_node_set_boost_unordered_enable_stats[enabled], transfers the internal statistical information from `other` iff `a == other.get_allocator()`, and always calls `other.reset_stats()`.
若 `a == other.get_allocator()`，则 `other` 的元素会直接转移到新容器；否则元素从 `other` 移动构造而来。
哈希函数与谓词从 `other` 移动构造，分配器从 `a` 复制构造。
若启用了统计功能：仅当 `a == other.get_allocator()` 时，从 `other` 转移内部统计信息；**始终调用** `other.reset_stats()`。

```c++ concurrent_node_set& operator=(concurrent_node_set&& other) noexcept(boost::allocator_traits<Allocator>::is_always_equal::value || boost::allocator_traits<Allocator>::propagate_on_container_move_assignment::value); ``` The move assignment operator. 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 `*this`; otherwise, inserts move-constructed copies of the elements of `other`. If statistics are xref:concurrent_node_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()`.

移动赋值运算符。销毁先前存在的元素，交换other的哈希函数与谓词；若Alloc::propagate_on_container_move_assignment存在且Alloc::propagate_on_container_move_assignment::value为true，则移动赋值other的分配器。若此时分配器与other.get_allocator()相等，直接将other的内部桶数组转移至*this；否则插入other元素的移动构造副本。若启用 xref:concurrent_node_set_boost_unordered_enable_stats [统计功能]，当且仅当最终分配器与other.get_allocator()相等时，从other转移内部统计信息，且始终调用other.reset_stats()。</allocator></allocator>

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键等价的元素时，才使用 `std::forward<k>(k)` 构造元素并插入到容器中。</k>

Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[EmplaceConstructible^] from `k`. Returns:;; `true` if an insert took place. Concurrency:;; Blocking on rehashing of `*this`. Notes:;; This overload only participates in overload resolution if `Hash::is_transparent` and `Pred::is_transparent` are valid member typedefs. 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.
要求：;; `value_type` 可通过 `k` 原位构造。
返回值：;; 若成功插入元素则返回 `true`。
并发特性：;; 会阻塞当前对象 `*this` 的扩容重哈希操作。
注意：;; 仅当 `Hash::is_transparent` 和 `Pred::is_transparent` 为合法成员别名时，该重载版本参与重载决议。库假定 `Hash` 可同时接收 `K` 与 `Key` 类型调用，且 `Pred` 是透明的。这支持异构查找，避免了实例化 `Key` 类型对象的开销。
