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.

	English 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`.
	Chinese (Simplified Han script) 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` 。 85/1670 · 167 Needs editing

	English 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.
	Chinese (Simplified Han script) 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。 126/4140 · 414 Needs editing

	Chinese (Simplified Han script) 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> 338/6900 · 690 Needs editing
