Automate the use of rustfmt in github actions

Ensure formatting is kept consistent, automating that process. Not sure if there's a point to adding clippy into the mix too

Maybe this helps? #78

Github actions will fail if it code is not correctly formatted. You could add cargo-husky to prevent committing unformatted code example

Cool! Actually, do you know if rustfmt or clippy is the standard? :o

[naomijub]

It is supposed to be rustfmt, but I don't know if they have merged as of now

Rust is a formatter while clippy is a linter:

I can apply clippy in a next PR as the project os too large to fix it all at once.
