Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Motion

Fields

time: u32

dx: f64

dy: f64

pointer relative motion event

The pointer has moved by a relative amount to the previous request.

Values are in the global compositor space.

MotionAbsolute

Fields

time: u32

x: u32

y: u32

x_extent: u32

y_extent: u32

pointer absolute motion event

The pointer has moved in an absolute coordinate frame.

Value of x can range from 0 to x_extent, value of y can range from 0 to y_extent.

Button

Fields

time: u32

button: u32

state: ButtonState

button event

A button was pressed or released.

Axis

Fields

time: u32

axis: Axis

value: f64

axis event

Scroll and other axis requests.

Frame

end of a pointer event sequence

Indicates the set of events that logically belong together.

AxisSource

Fields

axis_source: AxisSource

axis source event

Source information for scroll and other axis.

AxisStop

Fields

time: u32

axis: Axis

axis stop event

Stop notification for scroll and other axes.

AxisDiscrete

Fields

time: u32

axis: Axis

value: f64

discrete: i32

axis click event

Discrete step information for scroll and other axes.

This event allows the client to extend data normally sent using the axis event with discrete value.

Destroy

destroy the virtual pointer object

This is a destructor, once sent this object cannot be used any longer.

Trait Implementations
