Struct GestureRecognizer 

pub struct GestureRecognizer { /* private fields */ }

Stateful multi-touch gesture recognizer.

Feed it TouchContact events via process and it returns zero or more InputEvents that can be forwarded to MapState::handle_input.

Implementations

impl GestureRecognizer

pub fn new() -> Self

Create a new gesture recognizer with no active touches.

pub fn reset(&mut self)

Reset all gesture state (e.g. when the window loses focus).

pub fn finger_count(&self) -> usize

Number of fingers currently tracked.

pub fn process(&mut self, contact: TouchContact) -> Vec<InputEvent>

Process a single touch contact and return any resulting input events.

Typically returns 0–3 events (pan, zoom, rotate may fire simultaneously from a single two-finger move).
