In this chapter, you got acquainted with the standard Rust build tool, Cargo. We took a cursory look at initializing, building, and running the unit tests of your program. There are some tools beyond Cargo that can make the Rust coding experience smoother and safer, such as rustfmt, clippy, and racer. We saw how these may be integrated to a text editor by installing Visual Studio Code's Rusty Code extension. Finally, we founded a project that will be the basis for the game that we'll use to gain more skills.
The next chapter will be about unit testing. We'll start coding the book's project with a non-strict TDD style, finding out test cases where they are easy to find and filling in the implementation.
