Struct Model 

pub struct Model {
    pub rankdir: RankDir,
    pub nodes: Vec<Node>,
    pub edges: Vec<Edge>,
}

Fields

rankdir: RankDir

nodes: Vec<Node>

edges: Vec<Edge>

Implementations

impl Model

pub fn new(rankdir: RankDir) -> Self

pub fn index_of(&self, id: &NodeId) -> Option<usize>

Index of a node by id, for engines that key on position.

pub fn foldable_of(&self, id: &NodeId) -> Option<String>

The foldable group key of a node, if it is a group root. Only roots are foldable; members and ordinary nodes return None.

pub fn collapse(&self, collapsed: &HashSet<String>) -> Model

The render view for a set of collapsed groups. Every foldable root gets a fold marker (▾ open / ▸ … (N) closed); a collapsed group’s members and the edges touching them are dropped, so only the root stays in the flow. The root’s status reflects the worst of its members either way.

pub fn demo() -> Self

A CI-shaped sample used by tests and snapshots: lint/typos/deny fan into a foldable test matrix, which fans into the publish jobs.

Trait Implementations

impl Clone for Model

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Model

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
