Up until now, we needed to check all the details of the code by ourselves. This can often get out of control, since we cannot be checking each line of code. In this chapter, you will learn about the lints Rust brings us, both the ones enabled by default and the ones you can enable yourself.
Moreover, you will learn about a great tool, Clippy, that will give you many more lints you can use, and that can help you write much better code. In many cases, it will lint about performance pitfalls. In other cases, they will be potential errors or idiomatic conventions. It will also help you clean your code.
In this chapter, you will learn about the following topics:
- Linting in Rust
- Default lints
- Using and configuring Clippy
- Extra Clippy lints
