Struct Touch

pub struct Touch {
    pub device_id: DeviceId,
    pub phase: TouchPhase,
    pub location: PhysicalPosition<f64>,
    pub force: Option<Force>,
    pub id: u64,
}

Represents a touch event

Every time the user touches the screen, a new Start event with an unique identifier for the finger is generated. When the finger is lifted, an End event is generated with the same finger id.

After a Start event has been emitted, there may be zero or more Move events when the finger is moved or the touch pressure changes.

The finger id may be reused by the system after an End event. The user should assume that a new Start event received with the same id has nothing to do with the old finger and is a new finger.

A Cancelled event is emitted when the system has canceled tracking this touch, such as when the window loses focus, or on iOS if the user moves the device against their face.

Fields

device_id: DeviceId

phase: TouchPhase

location: PhysicalPosition<f64>

force: Option<Force>

Describes how hard the screen was pressed. May be None if the platform does not support pressure sensitivity.

Platform-specific

• Only available on iOS 9.0+ and Windows 8+.

id: u64

Unique identifier of a finger.

Trait Implementations

impl Clone for Touch

fn clone(&self) -> Touch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Touch

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

Formats the value using the given formatter.

impl PartialEq for Touch

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