Throughout this book, we have explained and used the concepts of Rust's Standard Library--the std crate. In this chapter, we will be discovering important standard modules that were not yet been covered (such as working with paths and files), and get a better grasp of working with collections.
We will discuss the following topics:
- Exploring std and the prelude module
- Collections - using hashmaps and hashsets
- Working with files
- Using Rust without the Standard Library
