Enum DeviceEventFilter 

pub enum DeviceEventFilter {
    Always,
    Unfocused,
    Never,
}

Defines which device events (raw input from mice, keyboards and other HID devices that is not bound to a specific window) the event loop should deliver to the application.

Listening to device events can be expensive, so the runtime filters them out by default while the application has no focused window. See crate::Runtime::set_device_event_filter.

Platform-specific

• Linux / macOS / iOS / Android: Unsupported, device events are always filtered out.

Variants

Always

Always filter out device events.

Unfocused

Filter out device events while the window is not focused.

Never

Report all device events regardless of window focus.
