Run rustfmt

[jwilm]

I started working on another patch last evening, and couldn't figure out what style to use in the code. There was a mix of 2 space indents, 4 space indents, arguments aligned at the call parens, arguments aligned starting at next indent, trailing commas in field lists or not, and etc.

This was run with the default rustfmt configuration. If that's not to your liking, I won't be offended if you want to close this and run it with your own config, or you can let me know what you want changed and I can update this and add a rustfmt config.

In any case, please consider accepting this PR or running rustfmt and committing it yourself; it would really help me and other new contributors to get started!

Thank you! 😁

That's cool, I've wanted to do this for a while. Should I merge this before your other PR or after? I.e. do they conflict?

[jwilm]

They probably conflict, but it's probably easier to merge this one first. I'll rebase the other one afterwards.

Thanks!

Apparently git is able to merge without conflict by first merging the rustfmt branch followed by the fix-warnings branch.
