//! A simple library for querying mouse and keyboard state without requiring
//! an active window. Currently works in Windows and Linux.
//!
//! ```no-run
//! use device_query::{DeviceQuery, DeviceState, MouseState, Keycode};
//!
//! let device_state = DeviceState::new();
//! let mouse: MouseState = device_state.get_mouse();
//! println!("Current Mouse Coordinates: {:?}", mouse.coords);
//! let keys: Vec<Keycode> = device_state.get_keys();
//! println!("Is A pressed? {}", keys.contains(&Keycode::A));
//! ```
