Struct RowRun 

pub struct RowRun {
    pub viewport: f32,
    pub anchor: usize,
    pub anchor_top: f32,
    pub gap: f32,
    pub density: f32,
}

Everything about a scaling list that is the same for all of its rows.

Held together rather than passed one by one because place_rows_with walks a run and every one of these is a property of the run, not of a row.

Fields

viewport: f32

The list’s full height, which is what the ramp is stated against.

anchor: usize

Which row the walk starts from — ScalingLazyListState.centerItemIndex.

anchor_top: f32

Where the anchored row’s own box starts. This is the one position the unscaled stack and the walk always agree on: the anchored row is never scaled, so its cursor and its slot are the same number.

gap: f32

Arrangement.spacedBy, between every pair of drawn boxes.

density: f32

Device pixels per unit; 0.0 works in continuous coordinates.
