Struct KnowledgeGraph 

pub struct KnowledgeGraph { /* private fields */ }

A simple in-memory knowledge graph for context extraction.

Stores triples and supports N-hop traversal.

Implementations

impl KnowledgeGraph

pub fn new() -> Self

Create an empty knowledge graph.

pub fn from_triples(triples: &[ContextTriple]) -> Self

Build a knowledge graph from a slice of triples.

pub fn add_triple(&mut self, triple: ContextTriple)

Add a single triple.

pub fn len(&self) -> usize

Number of triples in the graph.

pub fn is_empty(&self) -> bool

Whether the graph is empty.

pub fn neighbors(&self, entity: &str) -> Vec<&ContextTriple>

Get all triples where entity appears as subject or object.

pub fn triples_by_predicate(&self, predicate: &str) -> Vec<&ContextTriple>

Get all triples with a specific predicate.

pub fn all_triples(&self) -> &[ContextTriple]

Get all triples.
