Hi all,

Thank you so much for your work.

I would like to request adding a link to the Rust crate to the README.md.
Here is the link: https://github.com/delihiros/zengin

Thank you!

@delihiros Thanks for developing the Rust version!

If you wish, I can fork your repository as zengin-code/zengin-rs and pass commit privileges to you.

Additions to the README will be made at a later date.
