Code

I suppose it has something to do with "clone_into" since this was the last line I added. Before that compiling was successful.

         let w: u32 = (b.width - b.x).ceil() as u32;
            let h: u32 = (b.height - b.y).ceil() as u32;
            let mut pixels = vec![127 as u8; (w * h * 4) as usize];
            let fractal: Fractal = calculation::Fractal::new(
                0.0,
                0.0,
                3.0,
                512,
                4.0,
                w as i32,
                h as i32,
                calculation::Fractal::c_modulo,
                4,
                w as i32 *4,
            );
            let p: Arc<Mutex<FractalParams>> = Arc::clone(&fractal.params);
            let p2: MutexGuard<FractalParams> = p.lock().unwrap();
            p2.calculate_fractal();
            let p3 = p2.pixels.lock().unwrap();
            p3.clone_into(&mut pixels);
            let image_handle: Handle = image::Handle::from_pixels(w, h, pixels);

            (
                Primitive::Image { handle: image_handle, bounds: b },
