Struct AnchoredMomentum 

pub struct AnchoredMomentum {
    pub velocity: Option<f64>,
    pub anchor: Option<ScreenPoint>,
    pub decay: MomentumDecay,
    pub snap: Option<MomentumSnap>,
}

How a gesture’s zoom, bearing, or pitch keeps changing after release.

See mln_anchored_momentum in the C API reference.

Fields

velocity: Option<f64>

How fast the value changed at release: zoom levels per second for zoom, and degrees per second for bearing and pitch. The part moves only when this is set.

anchor: Option<ScreenPoint>

The screen point that the change keeps in place. Without one, the change keeps the center of the view in place.

decay: MomentumDecay

snap: Option<MomentumSnap>

Where the part settles. Without this, it stays where the gesture and its glide leave it.
