GitHub action

[Veetaha]

Would there be an interest to roll out a GitHub action for cargo-udeps so that adding this one to CI runs would be just a one-liner?
There is an awesome template by embark guys with their cargo-deny sanitizer we could use as a reference, which is nothing more than a Dockerfile and 3-4 lines of bash at it's core (link)
There is also an opened issue to think about somehow merging deny and udeps both together, but this is yet another topic :D

The action will probably reside in a separate repo (since it involves tagging versions of the action and this may interfere with cargo-udeps cli releases).

This is an interesting idea.

Was just looking for exactly this, +1 from me

I needed this so I took a stab at it, borrowing heavily from actions-rs. https://github.com/aig787/cargo-udeps-action. I'm happy to have it brought into the family if you want @est31.

@est31 I build a simple workflow for running cargo-udeps in GitHub Actions. It wouldn't have to build a dedicated action IMO.

However, installing cargo-udeps takes about 5 minutes. Could we reduce the overhead?

You could reduce it by caching built binary.

Yeah there is a Rust specific section in the github actions cache documentation.
