In this chapter, you learned about many crates that will make your life writing Rust code much easier. You learned how they can not only allow you to write less code, but that they can help you write faster code. We also saw how easy it is to use a crate from https://crates.io/, which gives us superpowers when using code written by others.

In the next chapter, you will learn how to develop your own macros, similar to the ones seen here, and you will also learn how to create your own procedural macros and plugins.
