Struct ScrollAxisRange 

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

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.

content_padding_start and content_padding_end are the container’s content padding at its top and bottom (or left and right) edges, in layout pixels. Content scrolls under that padding, where a bar may cover it, so a control a reader or the keyboard moves to is brought in past it.

Fields

value: f32

max_value: f32

reverse: bool

content_padding_start: f32

content_padding_end: f32

pub fn with_content_padding(self, start: f32, end: f32) -> ScrollAxisRange

The same range with the container’s content padding at its start and end edges, in layout pixels.
