Struct PenSample 

pub struct PenSample {
    pub pressure: f64,
    pub tilt: (f64, f64),
    pub eraser: bool,
}

What a stylus reported with one pointer event.

Fields

pressure: f64

How hard the tip is pressed, 0.0..=1.0: 0.0 while it hovers, and on a pen that reports no pressure.

tilt: (f64, f64)

Tilt in degrees from upright towards the window’s positive x and y axes, each within -90.0..=90.0: (0.0, 0.0) upright, and on a pen that reports no tilt.

eraser: bool

The eraser end is in use rather than the tip.

Implementations

impl PenSample

pub fn from_event(event: &WindowEvent) -> Option<PenSample>

The sample a WindowEvent::PenSample carries, None for any other event.

Trait Implementations

impl Clone for PenSample

fn clone(&self) -> PenSample

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PenSample

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

Formats the value using the given formatter.

impl Default for PenSample

fn default() -> PenSample

Returns the “default value” for a type.

impl PartialEq for PenSample

fn eq(&self, other: &PenSample) -> 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.

impl Copy for PenSample
