Excellent! Welcome and have fun!

I would imagine that the package authors start using the release async soon.
The release of async seemed like a big deal in the rust community.

Oh that's good! Maybe those can go in sooner than i3status-rust.
Smaller batches with the async libraries, dbus and inotify seem pretty
likely to be reused.

I'm not sure what to do for a new license, but that reminds me that
the importer doesn't understand the bsd-2 clause.

Thanks and happy hacking,
