Touch arguments

The id might be reused for different touches that do not overlap in time.

• Coordinates are normalized to support both touch screens and trackpads
• Supports both 2D and 3D touch
• The pressure direction vector should have maximum length 1

For 2D touch the pressure is pointed the z direction. Use .pressure() to get the pressure magnitude.

Fields

device: i64

A unique identifier for touch device.

id: i64

A unique identifier for touch event.

x: f64

The x coordinate of the touch position, normalized 0..1.

y: f64

The y coordinate of the touch position, normalized 0..1.

z: f64

The z coordinate of the touch position, normalized 0..1.

px: f64

The x coordinate of the touch pressure direction.

py: f64

The y coordinate of the touch pressure direction.

pz: f64

The z coordinate of the touch pressure direction.

is_3d: bool

Whether the touch is in 3D.

touch: Touch

The touch state.

Implementations

impl TouchArgs

pub fn new(
    device: i64,
    id: i64,
    pos: [f64; 2],
    pressure: f64,
    touch: Touch
) -> TouchArgs

Creates arguments for 2D touch.

pub fn new_3d(
    device: i64,
    id: i64,
    pos: [f64; 3],
    pressure: [f64; 3],
    touch: Touch
) -> TouchArgs

Creates arguments for 3D touch.

The pressure direction vector should have maximum length 1.

pub fn position(&self) -> [f64; 2]

The position of the touch in 2D.

pub fn position_3d(&self) -> [f64; 3]

The position of the touch in 3D.

pub fn pressure(&self) -> f64

The pressure magnitude, normalized 0..1.

pub fn pressure_3d(&self) -> [f64; 3]

The pressure vector in 3D.

Trait Implementations

impl Clone for TouchArgs

fn clone(&self) -> TouchArgs

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TouchArgs

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TouchArgs

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<TouchArgs> for Input

fn from(args: TouchArgs) -> Self

Converts to this type from the input type.

impl From<TouchArgs> for Motion

fn from(args: TouchArgs) -> Self

Converts to this type from the input type.

impl PartialEq<TouchArgs> for TouchArgs

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

impl Serialize for TouchArgs

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TouchArgs
