Yeah we haven't published a new version in a while. I believe this has been fixed on main, could you try cloning and building manually?

[sornas]

I've published 0.3.1 now, see if that one works better.

[sornas]

Please let me know if it still fails and I'll re-open!

[juristoeckli]

Tanks for working on this project.
it now works, but fails later during build. (it probably is somehow my fault :)

This is caused by an outdated compiler. feature(matches_macro) was merged in 1.42 and I belive we require 1.46 at this point. You need to update your compiler, for example with rustup update if you installed Rust via rustup (which I can't recommend enough if you haven't).
