Struct Gui

pub struct Gui {
    pub input: Input,
    /* private fields */
}

Acts as an intermediary between ggez and egui

use ggegui::{egui, Gui};
struct State {
    gui: Gui,
}

impl State {
    pub fn new(ctx: &mut Context) -> Self {
        Self {
            gui: Gui::new(ctx),
        }
    }
}

impl EventHandler for State {
    fn update(&mut self, ctx: &mut Context) -> GameResult {
        let gui_ctx = self.gui.ctx();

        egui::Window::new("Title").show(&gui_ctx, |ui| {
            ui.label("label");
            if ui.button("button").clicked() {
                println!("button clicked");
            }
        });
           self.gui.update(ctx);
        Ok(())
    }

    fn draw(&mut self, ctx: &mut Context) -> GameResult {
        let mut canvas = graphics::Canvas::from_frame(ctx, Color::BLACK);
        canvas.draw(
            &self.egui_backend,
            DrawParam::default().dest(glam::Vec2::ZERO),
        );
        canvas.finish(ctx)
    }
}
