	```c++ size_type insert(std::initializer_list<value_type> il); ```	```c++ size_type insert(std::initializer_list<value_type> il); ```</value_type>
:1017	Equivalent to [listing,subs="+macros,+quotes"]	等价于 [listing,subs="+macros,+quotes"]
:1024	Returns:;; The number of elements inserted.	返回值：;; 成功插入的元素个数。

	Insert Node	节点插入
	```c++ insert_return_type insert(node_type&& nh); ```	```c++ insert_return_type insert(node_type&& nh); ```
	If `nh` is not empty, inserts the associated element in the table if and only if there is no element in the table with a key equivalent to `nh.value()`. `nh` is empty when the function returns.	若 `nh` 非空，则当且仅当哈希表中不存在与 `nh.value()` 键等价的元素时，将其关联元素插入哈希表。函数返回时 `nh` 变为空。
:1037	Returns:;; An `insert_return_type` object constructed from `inserted` and `node`: +	返回值：;; 由 `inserted` 和 `node` 构造的 `insert_return_type` 对象。
:1038	If `nh` is empty, `inserted` is `false` and `node` is empty.	若 `nh` 为空，则 `inserted` 为 `false` 且 `node` 为空。
:1039	Otherwise if the insertion took place, `inserted` is true and `node` is empty.	若插入操作成功，则 `inserted` 为 true，且 `node` 为空。
:1040	If the insertion failed, `inserted` is false and `node` has the previous value of `nh`.	若插入操作失败，则 `inserted` 为 false ，且 `node` 保留 `nh` 的原值。
	Throws:;; If an exception is thrown by an operation other than a call to `hasher` the function has no effect. Concurrency:;; Blocking on rehashing of `*this`. Notes:;; Behavior is undefined if `nh` is not empty and the allocators of `nh` and the container are not equal.	若 `nh` 非空，则当且仅当容器中不存在与 `nh.value()` 等效的键时，插入其关联的元素。函数返回时 `nh` 为空。

	Inserts an object, constructed with the arguments `args`, in the table if there is no element in the table with an equivalent key. Otherwise, invokes `f` with a const reference to the equivalent element.	若哈希表中不存在键等价的元素，则使用参数 `args` 构造对象并插入表中；否则，以该等价元素的常量引用为参数调用函数 `f`。
	Requires:;; `value_type` is constructible from `args`. Returns:;; `true` if an insert took place. Concurrency:;; Blocking on rehashing of `*this`. Notes:;; The interface is exposition only, as C++ does not allow to declare a parameter `f` after a variadic parameter pack.	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。注意：;; 该接口仅为说明性用法，因为 C++ 不允许在可变参数包之后声明参数 `f`。

	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。
