Create a rustfmt.toml defining our whitespace/formatting standards
We currently have no style consensus for Rust code. It would be good to agree on something! We could agree on whatever the Rust people like (still a WIP last I checked) or we could modify that by creating a rustfmt.toml
.
We should also probably add a pre-commit hook for running rustfmt, since we have a pretty clean slate and we should keep it clean. :)
