So first things first, we need to download the source code. Racer is a utility to provide code completion for our software development tools. The Rust compiler is already quite strict, clippy goes a step further and helps prevent some things which are valid but bad practice.
Configuring Racer Racer is used for code completion suggestions so that while you are typing your code editor can give you suggestions for what to type. It should make a 'rustc--src.

Rustup knows exactly what version of the compiler you're using, and so it's got just the information that these tools need. It provides things like code completion, goto definitions, rich refactoring, and some other nice features.
Additional utilities Rustfmt - Writing well-formatted code When you are solving the exercise, you are free to choose any coding format you want.

Then you can test that racer works by doing a test run via the command line: racer complete std::io::B You should see several matches from this. Optionally you can map it to something more convenient, I use f nmap f :Autoformat Or you can instruct Vim to automatically format on save, which is only convenient if the formatter is fast enough. Our goal will be to have these lints ran alongside the build and test phase, as only running clippy after tests succeed may obscure the tips from clippy when a test fails tips that may deduce why tests failed. Now for the tricky part, you need to get the Visual C++ magic working in your environment.
