Struct SankeyLinkLayout 

pub struct SankeyLinkLayout {
    pub index: usize,
    pub source: usize,
    pub target: usize,
    pub value: f64,
    pub y0: f32,
    pub y1: f32,
    pub width: f32,
    pub source_width: f32,
    pub target_width: f32,
}

A link with computed layout.

Like d3-sankey, y0 and y1 are the vertical centers of the ribbon at the source and target end. Each end has its own width: the links of a node’s side share the node height in proportion to their values, so both sides of every node are always fully covered. On a balanced graph (incoming sum == outgoing sum everywhere) the two ends are equal; on an imbalanced one (e.g. sqrt-compressed values) the ribbon transitions smoothly between the two widths.

Fields

index: usize

source: usize

target: usize

value: f64

The flow value in the layout’s value space (scaled by SankeyValueScale; equals the raw input value under Linear).

y0: f32

y1: f32

width: f32

The nominal width from the global value scale, used by the layout relaxation; equals both end widths on a balanced graph.

source_width: f32

The ribbon width at the source end.

target_width: f32

The ribbon width at the target end.
