Struct ScrollInfo 

pub struct ScrollInfo {
    pub offset: f64,
    pub max_offset: f64,
    pub overscroll: f64,
}

A scroll observation snapshot handed to ScrollView::on_scroll.

offset is the clamped scroll position in [0, max_offset]; overscroll is the signed past-edge displacement (negative = pulled past the top, positive = pulled past the bottom), zero while the surface rests in range. During a drag past an edge, offset pins at the edge and overscroll carries the (resisted) pull.

Fields

offset: f64

The clamped scroll offset in [0, max_offset] (px scrolled down).

max_offset: f64

The maximum scroll offset (content − viewport, never negative).

overscroll: f64

Signed past-edge displacement: negative past the top, positive past the bottom, 0.0 while in range.
