Struct GraphLayout

Source

pub struct GraphLayout<N: Node> {
    pub positions: HashMap<N, LayoutPosition>,
    pub width: f64,
    pub height: f64,

Fields§

§positions: HashMap<N, LayoutPosition>

Node → position mapping

§width: f64

Width of the layout canvas

§height: f64

Height of the layout canvas
