Summary

In this chapter, we saw a lot of important things like how to use Cargo (through the Cargo.toml file), how to import new crates into a project, thanks to Cargo, and the basics for Rust modules handling. We even covered how to use iterators and read and write files, SDL2 basics like how to create a window and fill it with colors, and loading/creating new textures and images (thanks to the SDL2-image library!).

In Chapter 3, Events and Basic Game Mechanisms, we'll start the implementation of the tetris game, so be sure to master everything explained in this chapter before starting the next one!
