Struct ScrollAxisRange 

pub struct ScrollAxisRange {
    pub value: f32,
    pub max_value: f32,
    pub reverse: bool,
}

How far a container has scrolled along one axis and how far it can go.

This is Compose’s ScrollAxisRange (verticalScrollAxisRange, horizontalScrollAxisRange). A lazy list has no whole extent to give, so it reports the first visible item as the value and one more than that as the end while it can still scroll; a reader only needs to know whether it can page on.

Fields

value: f32

max_value: f32

reverse: bool
