Enum Overscroll 

pub enum Overscroll {
    Auto,
    Contain,
}

What a scroll gesture that starts over a scroller already at its limit does: CSS’s overscroll-behavior, spelled by the overscroll row.

A gesture picks its target when it starts: the innermost scroller under the pointer that can still move the way it goes. One at its limit is passed by, to the scroller around it — chaining — and Contain stops that: the gesture is this scroller’s, and moves nothing until it turns back. Only on the axes the node scrolls, so a scroll_y list that contains still passes a sideways swipe to the strip it sits in, where CSS would stop that too. Decided at the start only: a gesture that reaches a limit midway stops there whatever this says, as a browser’s does.

Variants

Auto

The gesture goes on to the scroller around this one when this one is at its limit that way.

Contain

A gesture that starts here stays here: a panel, a popup’s list or a sheet whose scrolling must never move the page behind it.
