emplace
原地构造
```c++ template<class... Args> bool emplace(Args&&... args); ```
```c++ template<class... args=""> bool emplace(Args&amp;&amp;... args); ```</class...>
Inserts an object, constructed with the arguments `args`, in the table if and only if there is no element in the table with an equivalent key.
当且仅当哈希表中不存在键等价的元素时，才使用参数 `args` 构造对象并插入到哈希表中。
Requires:;; `value_type` is constructible from `args`. Returns:;; `true` if an insert took place. Concurrency:;; Blocking on rehashing of `*this`.
要求：;; `value_type` 可由 `args` 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。

要求：;; `value_type` 支持拷贝插入。

当且仅当哈希表中不存在键等价的元素时，才将 `obj` 插入到哈希表中。
Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/MoveInsertable[MoveInsertable^]. Returns:;; `true` if an insert took place. Concurrency:;; Blocking on rehashing of `*this`.

Transparent Insert
透明插入
```c++ template<class K> bool insert(K&& k); ```
```c++ template<class k=""> bool insert(K&amp;&amp; k); ```</class>
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。

Insert Iterator Range
迭代器范围插入
```c++ template<class InputIterator> size_type insert(InputIterator first, InputIterator last); ```

Returns:;; The number of elements inserted.
