Runtime plugins

[zanciks]

Hello! I am trying to use egui/eframe for a desktop application. In doing so, I'd love to know if there is a way to create runtime plugins for it.
For instance, I was trying something simple like this:

// in main.rs, for instance 
use eframe::{App, Frame};
use eframe::egui::{self, Ui, Context};
use libloading::{Library, Symbol};
use std::fs;

pub struct Program {
	libs: Vec<Library>
}

impl Default for Program {
	fn default() -> Program {
		let plugins = fs::read_dir("libs/").expect("no plugins folder!");
		let mut libs = vec![];
		for plugin in plugins {
			unsafe{
				let path = plugin.unwrap().path();
				let lib = Library::new(path).expect("couldn't find dll");
				libs.push(lib);
			} 
		}
		Self { libs }
	}
}

impl App for Program {
	fn update(&mut self, ctx: &Context, _frame: &mut Frame) {
		for lib in &self.libs {
			unsafe {
				let func: Symbol<unsafe extern fn(Context)> = lib.get(b"render").unrwap();
				func(ctx.clone());
				}
		    }
}

and my precompiled plugin would look something like this:

#[no_mangle]
fn render(ctx: Context) {
	// render stuff goes here
}

and this all works great! It loads the plugin and starts the program!
However, attempting to USE the context in anyway results in a segmentation fault (as things tend to do when you use unsafe rust lol)
I've tried just about everything I can think of, including sending raw pointers, sending a mutable Ui, raw Ui pointers, etc.
I'm not sure what I can do to make this work, if its even possible.
Does anybody have experience with this? I would love to know how to possibly get this to work, even if its botched together :P

With this, if its even possible, I'd love to have these plugins run without their own window. Using something like egui_dock or egui_tiles to add plugins to different tabs. Of course, beggars can't be choosers, and I'd simply like to see this code run :P Thanks!!
