	Erases the element with key equivalent to `k` if it exists.	删除键与 `k` 等价的元素（若该元素存在）。
	Returns:;; The number of elements erased (0 or 1). 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. 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.	返回值：;; 删除的元素数量（0 或 1）。异常：;; 仅当 `hasher` 或 `key_equal` 抛出异常时才会抛出异常。注意：;; 仅当 `Hash::is_transparent` 和 `Pred::is_transparent` 为合法成员类型别名时，`template<class k="">` 重载才参与重载决议。标准库假定 `Hash` 可同时接收 `K` 与 `Key` 类型参数调用，且 `Pred` 是透明的。该机制支持异构查找，避免了实例化 `Key` 类型对象的开销。</class>

	Successively invokes `f` with references to each of the elements in the table, and erases those for which `f` returns `true`.	依次以表中每个元素的引用调用 `f`，并删除所有 `f` 返回 `true` 的元素。
	Returns:;; The number of elements erased. Throws:;; Only throws an exception if it is thrown by `f`.	返回值：;; 删除的元素数量。异常：;; 仅当 `f` 抛出异常时才会抛出异常。

	Parallel erase_if	并行条件擦除
	```c++ template<class ExecutionPolicy, class F> void erase_if(ExecutionPolicy&& policy, F f); ```	```c++ template<class executionpolicy,="" class="" f=""> void erase_if(ExecutionPolicy&& policy, F f); ```</class>
	Invokes `f` with references to each of the elements in the table, and erases those for which `f` returns `true`. Execution is parallelized according to the semantics of the execution policy specified.	以表中每个元素的引用调用 `f`，并删除所有 `f` 返回 `true` 的元素。执行过程将根据指定执行策略的语义进行并行化处理。
	Throws:;; Depending on the exception handling mechanism of the execution policy used, may call `std::terminate` if an exception is thrown within `f`. Notes:;; Only available in compilers supporting C++17 parallel algorithms. + + This overload only participates in overload resolution if `std::is_execution_policy_v<std::remove_cvref_t<ExecutionPolicy>>` is `true`. + + Unsequenced execution policies are not allowed.	异常：;; 依据所使用执行策略的异常处理机制，若 `f` 内部抛出异常，则可能调用 `std::terminate`。注意：;; 仅在支持 C++17 并行算法的编译器中可用。注意：;; 仅当 `std::is_execution_policy_v<std::remove_cvref_t<executionpolicy>>` 为 `true` 时，该重载才参与重载决议。注意：;; 不允许使用无序执行策略。</std::remove_cvref_t<executionpolicy>

	Swaps the contents of the table with the parameter.	将当前表与参数对象的内容进行交换。
	If `Allocator::propagate_on_container_swap` is declared and `Allocator::propagate_on_container_swap::value` is `true` then the tables' allocators are swapped. Otherwise, swapping with unequal allocators results in undefined behavior.	若 `Allocator::propagate_on_container_swap` 已声明且 `Allocator::propagate_on_container_swap::value` 为 `true`，则交换两个表的分配器。否则，使用不相等的分配器进行交换会导致未定义行为。
	Throws:;; Nothing unless `key_equal` or `hasher` throw on swapping. Concurrency:;; Blocking on `*this` and `other`.	异常：;; 除非 `key_equal` 或 `hasher` 在交换时抛出异常，否则不抛出任何异常。并发：;; 阻塞 `*this` 和 `other`。

	Extracts the element with key equivalent to `k`, if it exists.	返回值：;; 提取键与 `k` 等价的元素（若该元素存在）。
	Returns:;; A `node_type` object holding the extracted element, or empty if no element was extracted. 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. 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.	返回值：;; 存储提取元素的 `node_type` 对象，若未提取任何元素则为空。异常：;; 仅当 `hasher` 或 `key_equal` 抛出异常时才会抛出异常。注意：;; 仅当 `Hash::is_transparent` 和 `Pred::is_transparent` 为合法成员类型别名时，`template<class k="">` 重载才参与重载决议。标准库假定 `Hash` 可同时接收 `K` 与 `Key` 类型参数调用，且 `Pred` 是透明的。该机制支持异构查找，避免了实例化 `Key` 类型对象的开销。</class>

	```c++ template<class F> insert_return_type insert_or_visit(node_type&& nh, F f); template<class F> insert_return_type insert_or_cvisit(node_type&& nh, F f); ```	```c++ template<class f=""> insert_return_type insert_or_visit(node_type&& nh, F f); template<class f=""> insert_return_type insert_or_cvisit(node_type&& nh, F f); ```</class></class>
	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`。
	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` 。
	emplace_and_[c]visit	emplace_and_[c]visit
	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。
	Copy insert_and_[c]visit	复制 insert++_++and++_[++c++]++visit
	```c++ template<class F1, class F2> bool insert_and_visit(const value_type& obj, F1 f1, F2 f2); template<class F1, class F2> bool insert_and_cvisit(const value_type& obj, F1 f2, F2 f2); ```	```c++ template<class f1,="" class="" f2=""> bool insert_and_visit(const value_type& obj, F1 f1, F2 f2); template<class f1,="" class="" f2=""> bool insert_and_cvisit(const value_type& obj, F1 f2, F2 f2); ```</class></class>

	Iterator Range Constructor with Bucket Count and Hasher	带桶数和哈希函数的迭代器范围构造函数
	Invokes `f` with references to each of the elements in the table, and erases those for which `f` returns `true`. Execution is parallelized according to the semantics of the execution policy specified.	以表中每个元素的引用调用 `f`，并删除所有 `f` 返回 `true` 的元素。执行过程将根据指定执行策略的语义进行并行化处理。
	Throws:;; Nothing unless `key_equal` or `hasher` throw on swapping. Concurrency:;; Blocking on `*this` and `other`.	异常：;; 除非 `key_equal` 或 `hasher` 在交换时抛出异常，否则不抛出任何异常。并发：;; 阻塞 `*this` 和 `other`。

	Extracts the element `x` with key equivalent to `k`, if it exists and `f(x)` is `true`.	若键与 `k` 等价的元素 `x` 存在且 `f(x)` 为 `true`，则提取该元素。
	```c++ template<class H2, class P2> size_type merge(concurrent_node_set<Key, H2, P2, Allocator>& source); template<class H2, class P2> size_type merge(concurrent_node_set<Key, H2, P2, Allocator>&& source); ```	```c++ template<class h2,="" class="" p2=""> size_type merge(concurrent_node_set<key, h2,="" p2,="" allocator="">& source); template<class h2,="" class="" p2=""> size_type merge(concurrent_node_set<key, h2,="" p2,="" allocator="">&& source); ```</key,></class></key,></class>

	Returns:;; `static_cast<float>(size())/static_cast<float>(bucket_count())`, or `0` if `bucket_count() == 0`.	返回值：;; `static_cast<float>(size())/static_cast<float>(bucket_count())`，若 `bucket_count() == 0` 则返回 `0`。</float></float>
	Set max_load_factor	设置最大负载因子
	```c++ void max_load_factor(float z); ```	```c++ void max_load_factor(float z); ```
	Effects:;; Does nothing, as the user is not allowed to change this parameter. Kept for compatibility with `boost::unordered_set`.	效果：;; 不执行任何操作，因为不允许用户修改此参数。保留该函数是为了与 `boost::unordered_set` 保持兼容。
	When `size() == 0`, `rehash(0)` will deallocate the underlying buckets array.	效果：;; 当 `size() == 0` 时，调用 `rehash(0)` 会释放底层桶数组的内存。
