@tiagolobocastro this seems to be working. You will need to approve this workflow.

Cool it's running! Would you be able to add the missing bits which we had on travis, the docs and the check? Then there's the docs from paperclip.waffles.space, not sure how that works though.
Anyway if you don't have time for that I can try to add it later, it's a good start to get the CI back :)

Thanks for your efforts. And sure, I have a semi-working branch with clippy/rustfmt parts and then the docs will follow.

Added it here with clippy/rustfmt - #340
