Struct GraphRagEnricher 

pub struct GraphRagEnricher { /* private fields */ }

Graph-RAG enricher that adds graph context to search results

Implementations

impl GraphRagEnricher

pub fn new(config: GraphRagConfig) -> GraphRagEnricher

Create a new enricher with the given configuration

pub fn with_defaults() -> GraphRagEnricher

Create with default configuration

pub fn should_enrich(&self, graph: &SimpleEntityGraph) -> bool

Check if graph is large enough for enrichment

pub fn extract_graph_entities( &self, graph: &SimpleEntityGraph, text: &str, ) -> Vec<String>

Extract entities from text that exist in the graph

pub fn find_related_with_depth( &self, graph: &SimpleEntityGraph, start_entity: &str, max_depth: usize, ) -> Vec<RelationInfo>

Find related entities with depth limit and cycle detection

pub fn filter_relevant_relations( &self, relations: &[RelationInfo], query_entities: &[String], graph: &SimpleEntityGraph, ) -> Vec<RelationInfo>

Filter relations by relevance to query context

A relation is considered relevant if:

1. The target entity appears in query entities
2. The target entity shares context with query entities (common neighbors)
3. The relation type is high-priority (causes, depends_on, etc.)

pub fn summarize_path( &self, path: &[String], graph: &SimpleEntityGraph, ) -> String

Summarize a path with relationship types

Converts: [“payment”, “database”, “timeout”] To: “payment ─DEPENDS_ON→ database ─CAUSED_BY→ timeout”

pub fn relation_relevance_score( &self, relation: &RelationInfo, query_entities: &[String], query_neighbors: &HashSet<String>, ) -> u32

Calculate relevance score for a relation (exposed for testing)

pub fn analyze_query( &self, graph: &SimpleEntityGraph, query_entities: &[String], ) -> GlobalGraphInsights

Analyze query and build global insights

pub fn enrich_result( &self, graph: &SimpleEntityGraph, content: &str, query_entities: &[String], ) -> GraphEnrichment

Enrich a single search result with graph context

pub fn find_cross_result_insights( &self, graph: &SimpleEntityGraph, result_entities: &[Vec<String>], ) -> Vec<String>

Find structural insights between top results Now uses path summarization to show relationship types

pub fn cleanup_cache(&self)

Clear expired cache entries

pub fn cache_stats(&self) -> (usize, usize)

Get cache statistics
