 ## Personal Resources
 
 All the resources and assignments used by @PKUFlyingPig in this course are maintained in [PKUFlyingPig/CS110L - GitHub](https://github.com/PKUFlyingPig/CS110L)

+Due to the rapid evolution of Rust, the libraries used in the 2020 version of the course project are obsolete, so @fung-hwang tried to adapt these libraries (in November 2022). His adaptation advice and completed assignments are maintained in fung-hwang/CS110L-2020spr - GitHub. It is possible that Rust and these libraries will have changed again when you start to learn CS110L, but you can still refer to this repo for help.

 ## 资源汇总
 
 @PKUFlyingPig 在学习这门课中用到的所有资源和作业实现都汇总在 [PKUFlyingPig/CS110L - GitHub](https://github.com/PKUFlyingPig/CS110L) 中。

+在2022年 CS110L 没有开源作业源码的背景下，Rust 快速演进导致2020版本课程项目中所使用的库过于老旧。对此，@fung-hwang 尝试进行了适配（时间为2022.11)。其适配过程和作业实现都汇总在 fung-hwang/CS110L-2020spr - GitHub 中。也许当你开始本课程时 Rust 和这些库又发生了变化，但你仍可以参考并从中获得启发。
