How can I know what type of device was added?

[Angelo13C]

Guys, I am using winit to create a window and everything works fine.

Now I need to manage input in my application, and winit fires the DeviceEvent::Added when a new device is added, so that's great.
The problem is: how do I know what type of device was added? Was it a mouse, a keyboard..??

And is there any way to get extra info about it (something like how many buttons the mouse has)?

I received as an answer from other people that a device may send many types of event, but even knowing that a device could be a keyboard or a mouse, rather than knowing nothing would be useful.. (exposing an HID device struct?)

Internally winit (at least for windows) even knows what type of device the newly added one is.. Check line 56 at https://github.com/rust-windowing/winit/blob/76f158d3102aeb54e6c1c2ce2fd34dbe6b0daab1/src/platform_impl/windows/raw_input.rs)

Yeah, maybe we could add something like:

enum DeviceHint {
    Mouse,
    TouchScreen,
    Keyboard,
    ...
    Unknown,
}

impl DeviceId {
    fn hint(&self) -> DeviceHint;
}
