If `a == other.get_allocator()`, the elements of `other` are transferred directly to the new table; otherwise, elements are moved-constructed from those of `other`. The hash function and predicate are moved-constructed from `other`, and the allocator is copy-constructed from `a`. If statistics are xref:concurrent_flat_map_boost_unordered_enable_stats[enabled], transfers the internal statistical information from `other` iff `a == other.get_allocator()`, and always calls `other.reset_stats()`.

哈希函数与谓词从other移动构造，分配器从a拷贝构造。

Destroys previously existing elements, swaps the hash function and predicate from `other`, and move-assigns the allocator from `other` if `Alloc::propagate_on_container_move_assignment` exists and `Alloc::propagate_on_container_move_assignment::value` is `true`. If at this point the allocator is equal to `other.get_allocator()`, the internal bucket array of `other` is transferred directly to `*this`; otherwise, inserts move-constructed copies of the elements of `other`. If statistics are xref:concurrent_flat_map_boost_unordered_enable_stats[enabled], transfers the internal statistical information from `other` iff the final allocator is equal to `other.get_allocator()`, and always calls `other.reset_stats()`.

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.
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。

Inserts an object, constructed with the arguments `args`, in the table if there is no element in the table with an equivalent key. Otherwise, invokes `f` with a reference to the equivalent element; such reference is const iff `emplace_or_cvisit` is used.
若容器中无等价键的元素，则使用参数 args 构造对象并插入容器；
否则，将等价元素的引用传递给函数 f 并调用 —— 若使用的是 emplace_or_cvisit，则该引用为常量引用。
