Struct Graph 

pub struct Graph { /* private fields */ }

Immutable document graph with pre-built adjacency indices. Indices are automatically rebuilt on deserialization.

Implementations

impl Graph

pub fn new(nodes: IndexMap<String, Node>, edges: Vec<Edge>) -> Self

Build a graph from nodes and edges. Constructs adjacency indices.

pub fn node(&self, id: &str) -> Option<&Node>

pub fn nodes(&self) -> &IndexMap<String, Node>

pub fn edges(&self) -> &[Edge]

pub fn incoming_indices(&self, id: &str) -> &[usize]

Edge indices where target == id.

pub fn incoming_edges(&self, id: &str) -> Vec<&Edge>

Edges pointing to id.

pub fn outgoing_edges(&self, id: &str) -> Vec<&Edge>

Edges originating from id.

pub fn node_count(&self) -> usize

pub fn edge_count(&self) -> usize

Trait Implementations

impl Debug for Graph

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Graph

Deserialize nodes + edges, then automatically rebuild indices.

Older graph.json files without a schema_version field are treated as version 0, which the reader can still handle because the on-disk shape through v1 was backward-compatible (pure field additions). Any newer version surfaces a Deserialize error that propagates up as PARSE_ERROR — the user is instructed to nodex build --full to regenerate.

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Serialize for Graph

Serialize nodes + edges with a schema-version envelope. Indices are derived state and intentionally omitted.

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
