Struct DepGraphLayout 

pub struct DepGraphLayout {
    pub deep: bool,
    pub nodes: Vec<LaidNode>,
    pub edges: Vec<LaidEdge>,
    /* private fields */
}

The complete laid-out dependency graph in one display mode.

Fields

deep: bool

true when the layout is the full transitive closure (deep mode).

nodes: Vec<LaidNode>

edges: Vec<LaidEdge>

Implementations

impl DepGraphLayout

pub fn build( repos: &[String], edges: &[DepEdge], deep: bool, collapsed: &BTreeSet<String>, ) -> Self

Build a layout from the node set + the recorded edges.

• repos — every node to place (so isolated nodes still show).
• edges — from depends on to.
• deep — false → only direct edges; true → also synthesise the transitive- closure edges (flagged EdgeClass::Transitive).
• collapsed — nodes the user collapsed; their exclusively-owned subtree is dropped from both nodes and edges.

pub fn transitive_closure(repo: &str, edges: &[DepEdge]) -> BTreeSet<String>

The transitive dependency closure of repo over the recorded direct edges — every node reachable following from → to, excluding repo.

pub fn visible(&self) -> Vec<String>

The nodes currently visible (after applying the collapse set).

pub fn position(&self, repo: &str) -> Option<(usize, usize)>

Look up a node’s (col, row) by name.

pub fn direct_edges(&self) -> usize

pub fn transitive_edges(&self) -> usize

pub fn state_json(&self) -> Value

The introspection blob (LAW 6): mode, node positions, classified edges, and the collapse set — so a robot test sees exactly what is painted.
