Represents raw hardware events that are not associated with any particular window.

Useful for interactions that diverge significantly from a conventional 2D GUI, such as 3D camera or first-person game controls. Many physical actions, such as mouse movement, can produce both device and window events. Because window events typically arise from virtual devices (corresponding to GUI cursors and keyboard focus) the device IDs may not match.

Note that these events are delivered regardless of input focus.

MouseMotion

Fields

delta: (f64, f64)

(x, y) change in position in unspecified units.

Different devices may use different units.

Change in physical position of a pointing device.

This represents raw, unfiltered physical motion. Not to be confused with WindowEvent::CursorMoved.

MouseWheel

Fields

delta: MouseScrollDelta

Physical scroll event

Motion

Fields

axis: AxisId

value: f64

Motion on some analog axis. This event will be reported for all arbitrary input devices that winit supports on this platform, including mouse devices. If the device is a mouse device then this will be reported alongside the MouseMotion event.

Button

Fields

button: ButtonId

state: ElementState

Key(RawKeyEvent)

Trait Implementations

impl Clone for DeviceEvent

fn clone(&self) -> DeviceEvent

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeviceEvent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for DeviceEvent

fn eq(&self, other: &DeviceEvent) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
