Problem was `my_line` is owned by `_model` and cannot be moved.
Copying the entire `my_line` is apparently not possible, but what worked is making an element-wise copy of `my_line`, which is of type `(Point2, Hsl)`.
Using `iter()` to get an iterator and then `copied()` to copy the items did work.
The code of the `view()` function not looks like this:
fn view(app: &App, _model: &Model, frame: Frame) {
let draw = app.draw();
draw.background().color(GRAY);
draw.polyline().weight(3.0).points_colored(_model.my_line.iter().copied());
draw.to_frame(app, &frame).unwrap();
}
Thanks to `dzil123` in the nannou matrix chat for pointing this one out to me.
