	If `nh` is empty, does nothing. Otherwise, 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()`. Otherwise, invokes `f` with a const reference to the equivalent element.	若 `nh` 为空，则不执行任何操作。否则，当且仅当哈希表中不存在与 `nh.value()` 键等价的元素时，将其关联元素插入表中；否则，以该等价元素的常量引用为参数调用函数 `f`。
:1160	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。
:1161	If `nh` is empty, `inserted` is `false` and `node` is empty.	若 `nh` 为空，则 `inserted` 为 `false` 且 `node` 为空。
:1162	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。
:1163	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` or call to `f`, 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` 为空，则不执行任何操作；否则，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；否则，使用指向等效元素的常量引用调用 `f` 。

	Inserts an object, constructed with the arguments `args`, in the table if there is no element in the table with an equivalent key, and then invokes `f1` with a const reference to the newly created element. Otherwise, invokes `f2` 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，随后以新建元素的常量引用为参数调用函数 `f1`；否则，以该等价元素的常量引用为参数调用函数 `f2`。
	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 parameters `f1` and `f2` 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：;; 会阻塞当前对象的重哈希操作。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 `f1` 和 `f2` 参数。
