Struct EuvGestureState 

pub struct EuvGestureState {
    pub last_gesture: Signal<Option<EuvGesture>>,
    pub drag: Signal<Option<EuvDrag>>,
    pub pinch: Signal<Option<EuvPinch>>,
    pub on_start: Option<Rc<dyn Fn(Event)>>,
    pub on_move: Option<Rc<dyn Fn(Event)>>,
    pub on_end: Option<Rc<dyn Fn(Event)>>,
    pub on_cancel: Option<Rc<dyn Fn(Event)>>,
}

Live gesture state produced by EuvGestureRecognizer::use_gesture.

The three continuous signals are always mounted. The discrete last_gesture signal only changes when a gesture completes, so a view that renders it does not re-render on every touchmove.

Fields

last_gesture: Signal<Option<EuvGesture>>

The most recently completed single-finger gesture, or None when no gesture has completed since the hook was mounted.

drag: Signal<Option<EuvDrag>>

The in-progress drag, or None when no finger is dragging.

pinch: Signal<Option<EuvPinch>>

The in-progress two-finger pinch, or None when fewer than two fingers are down.

on_start: Option<Rc<dyn Fn(Event)>>

Handler for ontouchstart; begins a new gesture sequence.

on_move: Option<Rc<dyn Fn(Event)>>

Handler for ontouchmove; updates the drag and pinch signals.

on_end: Option<Rc<dyn Fn(Event)>>

Handler for ontouchend; completes the gesture.

on_cancel: Option<Rc<dyn Fn(Event)>>

Handler for ontouchcancel; abandons the gesture.
