Register property Change Callbacks from Rust?

[jonmmease]

Hi, I was wondering if it's currently possible to register Rust callbacks for execution when a property's value changes. I see that this is supported in Slint itself here.

And in looking at the slint_interpreter's ComponentInstance I see you can set the value of properties, and you can register custom implementations of callback's that are already defined in the slint file, but I don't see anything like a set_change_callback(prop_name: &str, ...)

If not currently possible, is this in scope?
