Struct PointerState

pub struct PointerState {
    pub time: u64,
    pub x: f32,
    pub y: f32,
    pub buttons: PointerButtons,
    pub contact_geometry: ContactGeometry,
    pub orientation: PointerOrientation,
    pub pressure: f32,
    pub tangential_pressure: f32,
}

A single pointer state.

Fields

time: u64

u64 nanoseconds real time.

The base time is not important, except by convention, and should generally be the same at least for states originating from the same device.

x: f32

x position.

Coordinate space is by convention.

y: f32

y position.

Coordinate space is by convention.

buttons: PointerButtons

Pressed buttons.

contact_geometry: ContactGeometry

Contact geometry.

orientation: PointerOrientation

Orientation.

pressure: f32

Normalized pressure in range 0..1.

Where pressure is not reported by the platform, it is always 0.5 when activated and 0.0 when not.

tangential_pressure: f32

Normalized ‘tangential pressure’ in range -1..1.

This is an arbitrary parameter and, despite its name, it may not originate from a pressure sensitive control. This is often controlled by something like a wheel on the barrel of an ‘airbrush’ style pen.

Trait Implementations

impl Clone for PointerState

fn clone(&self) -> PointerState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PointerState

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

Formats the value using the given formatter.

impl Default for PointerState

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for PointerState

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

Tests for self and other values to be equal, and is used by ==.

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

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