I think the Cargo source here is better than the binary tarball source. I eagerly await this package being in Mason.

I thought I had specified the source as being from cargo; do I need to change anything?

nope sorry I didn't communicate that clearly. I meant that I like what you did here. There was another PR for adding this package to Mason that used the binary tarballs as sources instead; I think the cargo approach is better.
