The states of the touch input state machine.

Variants

Nothing

Not tracking any touch point

WaitingForScript

A touchstart event was dispatched to the page, but the response wasn’t received yet. Contains the initial touch point.

DefaultPrevented

Script is consuming the current touch sequence; don’t perform default actions.

Touching

A single touch point is active and may perform click or pan default actions. Contains the initial touch location.

Panning

A single touch point is active and has started panning.

Fields

velocity: Vector2D<f32, DevicePixel>

Flinging

No active touch points, but there is still scrolling velocity

Fields

velocity: Vector2D<f32, DevicePixel>

cursor: DeviceIntPoint

Pinching

A two-finger pinch zoom gesture is active.

MultiTouch

A multi-touch gesture is in progress. Contains the number of active touch points.

Trait Implementations

impl Clone for TouchState

fn clone(&self) -> TouchState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TouchState

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

Formats the value using the given formatter.

impl PartialEq for TouchState

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