Rust Note #1: Use Clippy

In the future there should be more of these notes, but this is the first. It's just a thing I have learned about Rust in the past 2 years of using it.

Run Clippy against your Rust code to lint it for common mistakes and improve your code. It's a great way to learn new things about the language too.

I once wrote code like this...

let mut minifier_options = stylesheet::MinifyOptions::default();

minifier_options.targets = targets;

Clippy emitted a warning, "field assignment outside of initializer for an instance created with Default::default()" and recommended I use struct update syntax instead. So I changed the code to...

let minifier_options = stylesheet::MinifyOptions {
  targets,
  ..stylesheet::MinifyOptions::default()
};

The great thing is that I did not even know about struct update syntax and now I do.
