License is wrong, and it's better not to use MD5 as hash function to check integrity of files anymore. Here is a full patch with the changes I'd make to the PKGBUILD:

If you have some extra time you could also implement the check() function running the unit tests from upstream.

Hello! This PKGBUILD as it is fails to build in a clean chroot env. The reason is that in makedepends you should included python-maturin instead of just maturin. In addition, I think you should add python-pytz and python-tzdata to optdepends.
