I looked at this a few months ago, and it seemed that delta rs was in an experimental state, especially for writes
Let us know the outcome of your exploration 🙂

It doesn’t have all the latest features of Delta Lake. It’s also missing key things like delete/update/merge (you will have to overwrite your table or partitions to do that).
Also cool features like generated columns, z-order, column mapping are missing. Check the roadmap for more details https://github.com/delta-io/delta-rs/issues/1128
