Expand description

Represents a touch event

Every time the user touches the screen, a new TouchPhase::Started event with an unique identifier for the finger is generated. When the finger is lifted, an TouchPhase::Ended event is generated with the same finger id.

After a Started 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 Ended event. The user should assume that a new Started event received with the same id has nothing to do with the old finger and is a new finger.

A TouchPhase::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.

§Platform-specific

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+, Windows 8+, Web, and Android.
  • Android: This will never be None. If the device doesn’t support pressure sensitivity, force will either be 0.0 or 1.0. Also see the android documentation.
§id: u64

Unique identifier of a finger.

impl PartialEq for Touch

source§

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

This method tests for self and other values to be equal, and is used by ==.
