How to deal with egui and scripting?

[coderedart]

I have an overlay app which could use plugins. exposing some structs and functions usually is not that hard. but i keep wondering, how do i let them use egui so that they can have their own windows and stuff like that. I know i can make "wrapper" enum structs that they can use to define their gui like

pub enum Gui {
  Window{ width: i32, height: i32, title: String, sub_widgets: Vec<Gui>},
  TextLabel{ text: String },
  Button{ text: String, id: u32}, //a global hashmap shared between plugins/main app can contain a bool with that id as key, and i could set it to true if it was clicked
}

but i was wondering if anyone can figure out a better way to expose egui to plugins so they can take full advantage of it. I am open to anything honestly like rustpythong/rlua or libloading.

there's two questions here to be clear:

1. is it possible to directly share egui context with plugins smh and let them do what they want with it before they return it so i can call end_frame and draw.
2. if its not possible and i have to use some other way to define the gui, is there a clean (or even easy :) ) way to do this without making a separate DSL for it based on rustpythong or rlua or any rpc methods with json/grpc.
