Returns:;; A `node_type` object holding the extracted element, or empty if no element was extracted. Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`. Notes:;; The `template<class K>` overload only participates 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.

This enables heterogeneous lookup which avoids the cost of instantiating an instance of the `Key` type.类型作为参数，且 `Pred` 是透明的。这支持异构查找，从而避免实例化 `Key` 类型对象带来的性能开销。</class>

Extracts the element with key equivalent to `k`, if it exists.
Extracts the element with key equivalent to `k`, if it exists.若存在键与 `k` 等价的元素，则提取该元素。

If `Allocator::propagate_on_container_swap` is declared and `Allocator::propagate_on_container_swap::value` is `true` then the tables' allocators are swapped. Otherwise, swapping with unequal allocators results in undefined behavior.
If若声明了 `Allocator::propagate_on_container_swap` is declared and `Allocator::propagate_on_container_swap::value` is `true` then the tables' allocators are swapped. Otherwise, swapping with unequal allocators results in undefined behavior.且其值为 `true`，则交换两个表的分配器；否则，使用不相等的分配器进行交换会导致未定义行为。
