This looks like a nice tool, but I don't see a package request for it. Please submit one. This helps us document why packages are added.

For now I will mark this PR as a draft

[olymk2]

okay thanks @davidjharder I did not realise a request was needed, I have created one here #9221

I created this for myself but created the PR in case it was wanted as I went to the effort of packaging it.

[davidjharder]

Please use the %cargo_install macro if it works here

[olymk2]

I did try this initially it failed, is there a way to see what these macros are actually doing ?

[davidjharder]

Aside from error messages you can see the macro definitions here: https://github.com/getsolus/ypkg/blob/85340f6035c9ff516d749b078cd2d81c4e1c7d36/data/macros/actions/cargo.yaml

%cargo_install difft works for me

[Jaredy899]

Sorry for my two cents but this also needs a monitoring.yaml.

Also squash the commits into one commit. This is a good resource to use to figure out git. Also look at some of the pending PR's or accepted new package PR's to see our flow.
