Input map for winit.

                        println!(

                            input.mouse_move, input.mouse_pos

                        println!("released {:?}", input.binds(Click))
                    }

                    std::thread::sleep(std::time::Duration::from_millis(100));
                    // put at end of the loop because were done with inputs this frame.
                    input.init();
                }
                _ => (),
            }
        })
        .unwrap();
}

Above example doesnt work on some platforms due to a lack of rendered graphics.
