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.

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.
Although functionally equivalent to individually invoking xref:concurrent_flat_map_cvisit[`尽管功能上等价于对每个键单独调用 [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.，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。
