Struct TemporalGraphRag 

pub struct TemporalGraphRag { /* private fields */ }

A lightweight retrieval engine that wraps TemporalKnowledgeGraph and scores triples by keyword overlap with a natural-language question.

Implementations

impl TemporalGraphRag

pub fn new() -> Self

Create an empty engine.

pub fn ingest_event( &mut self, subject: &str, predicate: &str, object: &str, timestamp: i64, confidence: f64, )

Ingest a new event into the underlying knowledge graph.

timestamp is the Unix-ms start time; the triple is treated as “still valid” (no valid_to).

pub fn query( &self, question: &str, timestamp: i64, top_k: usize, ) -> Vec<TemporalTriple>

Retrieve up to top_k triples valid at timestamp that are most relevant to question, ranked by keyword overlap score.

pub fn summarize_entity_history(&self, entity: &str) -> EntityHistory

Summarise all historical appearances of entity in the knowledge graph.

pub fn cache_embedding(&mut self, entity: &str, embedding: Vec<f32>)

Store an embedding vector for entity in the cache.

pub fn get_embedding(&self, entity: &str) -> Option<&Vec<f32>>

Retrieve a cached embedding, if present.

pub fn event_count(&self) -> usize

Number of events ingested.

Trait Implementations

impl Default for TemporalGraphRag

fn default() -> Self

Returns the “default value” for a type.
