Once we have built the library, though, we might encounter a challenge, which is how do we handle serialization for these complex data types? The core problem is that we may need to customize how we serialize deeply nested fields, like DateTime or Vec. And beyond that, we will likely want to ensure that our serialization scheme is consistent across the entire application.
人们常常有这样的体验：玩游戏、聊天、看电影时，时间像飞一样过去；无聊、焦虑、等待时，时间像被拉长。根据我国科学家提出的新理论，这并不是心理作用那么简单，而是因为不同状态下大脑收集到的信息量不同。快乐兴奋时，动作和行为信息繁多，大脑忙着“计时”，自然觉得时间很快；而无聊时，整个身体都处于消极怠慢状态，大脑计时的“节拍器”慢下来。，详情可参考PG官网

Switching to the metallurgical microscope in a top-down view, looking at a good bond first, we can see a rough textured surface on the gold contact pad, with the gold wire coming in from one side and compressed into a crescent shape by the ball-bonding capillary (hence why some sources refer to the second bond as a “crescent bond”). The gold wire and gold pad appear to be well connected, and a deep circular indentation is visible in the pad which goes through the gold into a silvery base metal.
