Struct Scroll 

pub struct Scroll {
    pub axis: ScrollAxis,
    pub flags: ScrollFlags,
    pub range: Option<ScrollRange>,
    pub position: Option<ScrollPosition>,
}

Scroll semantics of a node that scrolls: the axis, whether it can scroll back toward the start of its content and forward toward its end from where it is, and, where the platform reports them, the range its content spans and the part of that range inside its viewport, both in the range’s unit.

Fields

axis: ScrollAxis

flags: ScrollFlags

range: Option<ScrollRange>

The range the content spans, when the platform reports one.

position: Option<ScrollPosition>

The part of range inside the viewport, when known; never present without a range.
