	English 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.
	Chinese (Simplified Han script) 返回值：访问过的元素数量（0 或 1）。注意：template<class k,="" class="" f=""> 形式的重载仅在 Hash::is_transparent 与 Pred::is_transparent 为合法成员别名时才参与重载决议。库假定 Hash 可同时用于 K 类型与 Key 类型，且 Pred 是透明的。这支持异构查找，避免了实例化 Key 类型对象带来的开销。</class> 207/4270 · 427 Needs editing

	English Although functionally equivalent to individually invoking xref:concurrent_flat_map_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_flat_map_constants[`bulk_visit_size`] to enjoy a performance gain: beyond this size, performance is not expected to increase further.
	Chinese (Simplified Han script) 尽管功能上等价于对每个键单独调用 [c]visit，但批量访问因内部流线型优化，通常性能更高。建议 std::distance(first,last) 至少达到 bulk_visit_size 阈值时再使用，以获得性能提升；超过该大小后，性能不会进一步提升。 130/4140 · 414 Needs editing

	English 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.
	Chinese (Simplified Han script) 要求：`FwdIterator` 需满足 https://en.cppreference.com/w/cpp/named_req/ForwardIterator[遗留向前迭代器^] 要求（{cpp}11 至 {cpp}17），或满足 https://en.cppreference.com/w/cpp/iterator/forward_iterator[`std::forward_iterator`^] 要求（{cpp}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` 是有效的成员 typedef。在后一种情况下，库假定 `Hash` 可同时以 `K` 和 `Key` 调用，且 `Pred` 是透明的。该机制支持异构查找，从而避免实例化 `Key` 类型的开销。返回：被访问的元素数量。</fwditerator> 471/6900 · 690 Needs editing
