Crate device_query

A simple library for querying mouse and keyboard state without requiring an active window. Currently works in Windows, Linux, and macOS.

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));

It’s also possible to listen for events.

 use device_query::{DeviceEvents, DeviceEventsHandler};
 use std::time::Duration;

 let device_state = DeviceEventsHandler::new(Duration::from_millis(10))
    .expect("Failed to start event loop");

 // Register a key down event callback
 // The guard is used to keep the callback alive
 let _guard = device_state.on_mouse_move(|position| {
    println!("Mouse position: {:#?}", position);
 });

 // Keep the main thread alive
 loop {}
