Rust packaging coordination

[John Soo]

Hello guix and rust packagers,

I’m curious if anyone else is working on packaging rust apps.  I have been 
working on a patch set for tokei and it’s getting close to done.

I would not like it if I had to rebase all 50 patches and I wouldn’t want 
anyone else to have to rebase theirs. So if you are working on any rust 
packages, maybe we should coordinate to make it less painful to merge.

Thanks!

John
