Throws:;; Doesn't throw an exception unless it is thrown by the copy constructor or copy assignment operator of `key_equal` or `hasher`. Notes:;; The exception specifications aren't quite the same as the C++11 standard, as the equality predicate and hash function are swapped using their copy constructors.

备注：;; 异常规范与 C++11 标准不完全相同，因为相等谓词和哈希函数是通过它们的复制构造函数进行交换的。

If `Allocator::propagate_on_container_swap` is declared and `Allocator::propagate_on_container_swap::value` is `true` then the containers' allocators are swapped. Otherwise, swapping with unequal allocators results in undefined behavior.
If如果 `Allocator::propagate_on_container_swap` is declared and已声明且 `Allocator::propagate_on_container_swap::value` is为 `true` then the containers' allocators are swapped. Otherwise, swapping with unequal allocators results in undefined behavior.，则交换两个容器的分配器。否则，使用不相等的分配器进行交换将导致未定义行为。

Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`. + + In this implementation, this overload doesn't call either function object's methods so it is no throw, but this might not be true in other implementations. Notes:;; This method was implemented because returning an iterator to the next element from erase was expensive, but the container has been redesigned so that is no longer the case. So this method is now deprecated.

在此实现中，此重载不会调用任一函数对象的方法，因此不会抛出异常，但在其他实现中可能并非如此。
备注：;; 之所以实现此方法，是因为从 `erase` 返回下一个元素的迭代器开销较大，但容器已经过重新设计，情况不再如此。因此，此方法现已废弃。
