	If an element `x` exists with key equivalent to `k`, invokes `f` with a const reference to `x`.	若存在键与 `k` 等价的元素 `x`，则使用指向 `x` 的常量引用调用 `f`。
	Returns:;; The number of elements visited (0 or 1). Notes:;; The `template<class K, class F>` overloads only participate 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：;; 访问过的元素数量（0 或 1）。注意：;; 仅当 `Hash::is_transparent` 与 `Pred::is_transparent` 为合法成员别名时，`template<class k,="" class="" f="">` 重载版本才会参与重载决议。库假定 `Hash` 可同时用于 `K` 与 `Key` 类型，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。</class>

	Bulk visit	批量访问
	```c++ template<class FwdIterator, class F> size_t visit(FwdIterator first, FwdIterator last, F f); template<class FwdIterator, class F> size_t visit(FwdIterator first, FwdIterator last, F f) const; template<class FwdIterator, class F> size_t cvisit(FwdIterator first, FwdIterator last, F f) const; ```	```c++ template<class fwditerator,="" class="" f=""> size_t visit(FwdIterator first, FwdIterator last, F f); template<class fwditerator,="" class="" f=""> size_t visit(FwdIterator first, FwdIterator last, F f) const; template<class fwditerator,="" class="" f=""> size_t cvisit(FwdIterator first, FwdIterator last, F f) const; ```</class></class></class>
	For each element `k` in the range [`first`, `last`), if there is an element `x` in the container with key equivalent to `k`, invokes `f` with a const reference to `x`.	对范围 ++[++`first`, `last`) 内的每个元素 `k` ，若容器中存在键等价于 `k` 的元素 `x` ，则使用指向 `x` 的常量引用调用 `f` 。
	Although functionally equivalent to individually invoking xref:concurrent_node_set_cvisit[`[c\]visit`] for each key, bulk visitation performs generally faster due to internal streamlining optimizations. It is advisable that `std::distance(first,last)` be at least xref:#concurrent_node_set_constants[`bulk_visit_size`] to enjoy a performance gain: beyond this size, performance is not expected to increase further.	尽管功能上等同于对每个键单独调用 `[c]visit`，但批量访问因内部优化通常性能更高。建议 `std::distance(first,last)` 至少达到 `bulk_visit_size` 以获得性能提升；超过该大小后，性能预计不会进一步提升。
	Requires:;; `FwdIterator` is a https://en.cppreference.com/w/cpp/named_req/ForwardIterator[LegacyForwardIterator^] ({cpp}11 to {cpp}17), or satisfies https://en.cppreference.com/w/cpp/iterator/forward_iterator[std::forward_iterator^] ({cpp}20 and later). For `K` = `std::iterator_traits<FwdIterator>::value_type`, either `K` is `key_type` or else `Hash::is_transparent` and `Pred::is_transparent` are valid member typedefs. In the latter case, 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. Returns:;; The number of elements visited.	要求：;; `FwdIterator` 是传统前向迭代器（C++11 至 C++17），或满足 `std::forward_iterator` 概念（C++20 及更高版本）。对于 `K = std::iterator_traits<fwditerator>::value_type`，要么 `K` 是 `key_type`，要么 `Hash::is_transparent` 和 `Pred::is_transparent` 是合法的成员别名。在后一种情况下，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。返回值：;; 被访问的元素数量。</fwditerator>
