Enum ScalePhase 

pub enum ScalePhase {
    Begin,
    Update,
    End,
}

The lifecycle phase of a scale (pinch/zoom) gesture.

No Cancel: every shipped source — the desktop ctrl/⌘+wheel mapping and macOS’s PinchGesture — reports a clean bracket (or, for an ordinary notch wheel, a lone Update with no bracket at all), so there is nothing yet for a cancelled variant to mean. Widened the day a source needs one.

Variants

Begin

The gesture began.

Update

The gesture continued; the event’s scale_delta/focal/velocity describe this increment.

End

The gesture ended normally.
