Struct Graph 

pub struct Graph {
    pub nodes: NodeStorage,
    pub csr: CsrGraph,
    pub edge_plasticity: EdgePlasticity,
    pub strings: StringInterner,
    pub id_to_node: HashMap<InternedStr, NodeId>,
    pub generation: Generation,
    pub pagerank_computed: bool,
    pub finalized: bool,
}

The complete property graph. Owns all storage. Mutation methods increment generation for desync detection (FM-PL-006).

Fields

nodes: NodeStorage

csr: CsrGraph

edge_plasticity: EdgePlasticity

strings: StringInterner

id_to_node: HashMap<InternedStr, NodeId>

Maps interned external ID -> internal NodeId.

generation: Generation

Monotonic counter incremented on every structural mutation.

pagerank_computed: bool

finalized: bool

Implementations

impl Graph

pub fn new() -> Self

pub fn with_capacity(node_cap: usize, edge_cap: usize) -> Self

pub fn add_node( &mut self, external_id: &str, label: &str, node_type: NodeType, tags: &[&str], last_modified: f64, change_frequency: f32, ) -> M1ndResult<NodeId>

Add a node. Returns its NodeId. Increments generation. Replaces: engine_v2.py PropertyGraph.add_node()

pub fn add_edge( &mut self, source: NodeId, target: NodeId, relation: &str, weight: FiniteF32, direction: EdgeDirection, inhibitory: bool, causal_strength: FiniteF32, ) -> M1ndResult<EdgeIdx>

Add an edge. Validates source/target existence (FM-ACT-011). Increments generation. Replaces: engine_v2.py PropertyGraph.add_edge()

pub fn finalize(&mut self) -> M1ndResult<()>

Build CSR forward + reverse adjacency. Compute PageRank. Must be called before any query. Sets finalized = true. Replaces: engine_fast.py FastPropertyGraph.finalize()

pub fn num_nodes(&self) -> u32

Number of nodes.

pub fn num_edges(&self) -> usize

Number of edges (forward CSR).

pub fn resolve_id(&self, external_id: &str) -> Option<NodeId>

Resolve external string ID to NodeId.

pub fn set_node_provenance( &mut self, node: NodeId, provenance: NodeProvenanceInput<'_>, )

pub fn merge_node_provenance( &mut self, node: NodeId, incoming: NodeProvenanceInput<'_>, )

pub fn resolve_node_provenance(&self, node: NodeId) -> ResolvedNodeProvenance

pub fn avg_degree(&self) -> f32

Average out-degree.
