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 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
