Enum Tool 

pub enum Tool {
    Finger,
    Pointer {
        button: PointerButton,
    },
    Stylus {
        pressure: Option<u16>,
        tilt: Option<UnitAngle>,
        azimuth: Option<UnitAngle>,
    },
}

Tool/instrument used for touch interaction

Variants

Finger

Finger or unknown tool

Pointer

Virtual pointing device (e.g., mouse cursor)

Fields

button: PointerButton

The button pressed on the virtual pointer

Stylus

Passive or active stylus

Fields

pressure: Option<u16>

Pressure, in grams

tilt: Option<UnitAngle>

Tilt angle

0 degrees is a vector normal to the screen, and 90 degrees is parallel to the screen.

azimuth: Option<UnitAngle>

Azimuth angle

0 degrees points up to the top of the screen in its default orientation.

Trait Implementations

impl Clone for Tool

fn clone(&self) -> Tool

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tool

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

Formats the value using the given formatter.

impl Hash for Tool

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Tool

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