Struct ExpressionGraph 

pub struct ExpressionGraph {
    pub nodes: Vec<VariableNode>,
    pub edges: Vec<DependencyEdge>,
}

Expression graph representing variable dependencies within expressions

Fields

nodes: Vec<VariableNode>

Nodes representing variables only (no operators or constants)

edges: Vec<DependencyEdge>

Edges representing dependencies between variables

Implementations

impl ExpressionGraph

pub fn adjacency(&self, name: &str) -> Vec<String>

The UNDIRECTED neighbourhood of name — its predecessors together with its successors (esm-libraries-spec §4.8.3), sorted. An unknown name resolves to [].

pub fn predecessors(&self, name: &str) -> Vec<String>

The variables an edge points FROM into name, sorted.

pub fn successors(&self, name: &str) -> Vec<String>

The variables name points at, sorted.

pub fn to_dot(&self) -> String

Export graph to DOT format for Graphviz

Returns

• String - DOT representation of the expression graph

pub fn to_mermaid(&self) -> String

Export graph to Mermaid format

Returns

• String - Mermaid representation of the expression graph

pub fn to_json_graph(&self) -> String

Export graph as the JSON adjacency list of esm-libraries-spec §4.8.3.

Returns

• String - {"nodes": […], "edges": […], "adjacency": {…}}
