Struct Touchscreen 

pub struct Touchscreen<OT: ConnectionTransport> { /* private fields */ }

BiDi Touchscreen implementation for simulating multi-touch gestures.

Touchscreen manages multiple touch points simultaneously, allowing you to simulate complex multi-touch gestures like pinch-to-zoom, multi-finger swipes, and other touch interactions.

Examples

let touchscreen = Arc::new(Touchscreen::new(session));

// Simulate a pinch gesture with two fingers
let touch1 = touchscreen.touch_start(100.0, 200.0, &context, None).await?;
let touch2 = touchscreen.touch_start(300.0, 200.0, &context, None).await?;

// Move fingers closer together
touch1.move_to(150.0, 200.0, &context).await?;
touch2.move_to(250.0, 200.0, &context).await?;

// Release both touches
touch1.end(&context).await?;
touch2.end(&context).await?;

Implementations

impl<OT: ConnectionTransport> Touchscreen<OT>

pub fn new(session: Arc<Mutex<Session<OT>>>) -> Self

Creates a new Touchscreen instance.

pub async fn touch_start( self: &Arc<Self>, x: f64, y: f64, context: &BrowsingContext, options: Option<TouchMoveOptions>, ) -> Result<TouchHandle<OT>, InputError>

Start a new touch at the given position and return a handle to control it.

Creates a new touch point and immediately performs a touch down event at the specified coordinates. Returns a TouchHandle that can be used to move or end the touch.

Arguments

• x - X coordinate in pixels where the touch starts
• y - Y coordinate in pixels where the touch starts
• context - The browsing context to perform the touch in
• options - Optional touch movement options

Returns

A TouchHandle that represents this touch point and can be used to control its movement.

Trait Implementations

impl<OT: ConnectionTransport> Clone for Touchscreen<OT>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
