Examples of calling Dyon from Rust?

I think the tutorial is supposed to demonstrate how to call Dyon scripts from Rust and pass values back and forth, but I'm pretty dense. Is there an example of calling a Dyon function in a .dyon file from Rust, calling Rust functions while inside Dyon code, and passing data bidirectionally?

The documentation on the Dyon language is solid, but I'm trying to find more guidance on interop.



Any news?

Thanks to anyone who knows
