Struct EdgeLayout 

#[non_exhaustive]
pub struct EdgeLayout {
    pub from: String,
    pub to: String,
    pub desc_index: usize,
    pub waypoints: Vec<Point>,
    pub broken: bool,
}

Routing of one edge: a waypoint polyline from the source card border to the target card border (endpoints inclusive).

Renderers draw straight polylines or splines through the waypoints; multi-rank edges carry one interior waypoint per crossed rank gap.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

from: String

Source node id, echoed from the input.

to: String

Target node id, echoed from the input.

desc_index: usize

Index of this edge in GraphDesc::edges, so caller metadata (label/style) maps back even for duplicate from/to pairs.

waypoints: Vec<Point>

Polyline in cells, source border first, target border last.

broken: bool

True when the cycle-breaking heuristic reversed this edge to obtain a DAG. The polyline still runs from from to to (it travels against the flow axis); it is MARKED, never silently reordered, so renderers can style back edges distinctly.

Implementations

impl EdgeLayout

pub fn new( from: impl Into<String>, to: impl Into<String>, desc_index: usize, waypoints: Vec<Point>, ) -> Self

Construct an edge routing (downstream construction path).

pub fn broken(self) -> Self

Mark this edge as cycle-broken (builder style).
