Struct NodeMap 

pub struct NodeMap {
    pub graphs: IndexMap<String, GraphNodeMap>,
}

The complete node map: one GraphNodeMap per named graph plus @default.

Fields

graphs: IndexMap<String, GraphNodeMap>

Graph name → per-graph node map. Always contains at least @default.

Implementations

impl NodeMap

pub fn new() -> Self

Create a new node map, pre-seeded with a @default graph.

pub fn get_or_create_graph(&mut self, graph_name: &str) -> &mut GraphNodeMap

Get the mutable reference to a graph, creating it if absent.

pub fn default_graph(&self) -> &GraphNodeMap

Shorthand accessor for the @default graph.

pub fn default_graph_mut(&mut self) -> &mut GraphNodeMap

Mutable shorthand accessor for the @default graph.
