Task: rustfmt

[dhardy]

We should apply rustfmt to the project, probably with #[rustfmt::skip] in some places, and add a CI check. It's going to conflict with a bunch of open PRs, but we always have some.

@MichaelOwenDyer are you interested?

[MichaelOwenDyer]

Sure thing. How do you feel about a pre-commit hook as well?

[dhardy]

Thanks. While format-before-commit is good practice, I'm not keen on the idea of tools changing code right before a commit, so no.

[dhardy]

Sorry, it's probably worth getting #1424 sorted before a more general reformat.

It's also worth to add Clippy job to CI (with a fixed toolchain version) and fix existing warnings (29 on current Nightly) in the same PR.

I ran rustfmt locally to see how severe the changes would be and it looks generally quite manageable, I only identified a couple files where we might want to sprinkle in #[rustfmt::skip]. I'll wait for #1424 to be merged before opening a PR.

Good idea 👍🏽
