Struct LinkData 

pub struct LinkData {
    pub source: String,
    pub target: String,
    pub kind: LinkKind,
    pub directed: bool,
    pub branch_index: Option<usize>,
    pub branch_active: Option<bool>,
}

A single edge in the D3 graph.

directed is true when this specific link’s direction is known and should render with an arrowhead from source to target; false renders it as a plain undirected line. This is a per-link fact, not a sheet-wide one: a cell ↔ relationship link is directed only once that relationship has a selected method, so one relationship having a cached plan says nothing about another relationship (or a currently-inactive conditional branch’s relationship) that doesn’t. A match cell → conditional link is always directed — evaluating a conditional’s match expression doesn’t depend on any relationship ever being planned. Control edges are always directed too — from a conditional node to a relationship, or, when a branch has more than one relationship, from the conditional to an intermediate Branch node and from that node to each relationship — and styled by branch_index and branch_active.

Fields

source: String

Stable string ID of the source node.

target: String

Stable string ID of the target node.

kind: LinkKind

The kind of link, determining its visual rendering.

directed: bool

true if this link’s direction is known and should render with an arrowhead.

branch_index: Option<usize>

Branch index for Control links; None for Constraint links and default-branch control links.

branch_active: Option<bool>

true if this branch is currently active; None for Constraint links.
