Send pull requests :) I haven't had much time to work on this in a while and probably won't get back to it for a while either. The rust code isn't production ready by any means. The python code works for me, but the rust stuff is not in a stable working state yet. It's very much a WIP. The rust server that holds the decryption key in memory worked for me once, but I haven't gotten around to testing it much beyond that.

So if you want the rust version to work... Send pull requests or be very patient.

Thanks for the current rust code. I will try ;)

• thanks for the good work on BW client for rust. I now have working src to learn from rust programming from your code.

Awesome! send the code?! :)

[T.J. Yang]

no rust code, still trying to understand your good rust code. What I did was st some crates adjusting in cargo.toml to finish crago build. I will re-fork and generate cleaner pull request.
