Struct GraphRAGHandler 

pub struct GraphRAGHandler { /* private fields */ }

Thread-safe GraphRAG handler

Implementations

impl GraphRAGHandler

pub fn new() -> Self

Create a new GraphRAG handler

pub async fn is_initialized(&self) -> bool

Check if GraphRAG is initialized

pub async fn initialize(&self, config: Config) -> Result<()>

Initialize GraphRAG with configuration

pub async fn load_document_with_options( &self, path: &Path, rebuild: bool, ) -> Result<String>

Load a document into the knowledge graph

Arguments

• path - Path to the document to load
• rebuild - If true, clears existing graph AND documents before loading (forces complete rebuild)

pub async fn clear_graph(&self) -> Result<String>

Clear the knowledge graph (preserves documents and chunks)

pub async fn rebuild_graph(&self) -> Result<String>

Rebuild the knowledge graph from existing documents

This clears the graph and re-extracts entities and relationships from all loaded documents. Useful after changing configuration or to fix issues with the graph.

pub async fn query_with_raw( &self, query_text: &str, ) -> Result<(String, Vec<String>)>

Execute a query and return both LLM answer and raw search results

Returns a tuple of (llm_answer, raw_results)

pub async fn query_explained( &self, query_text: &str, ) -> Result<QueryExplainedResult>

Execute a query and return explained answer with sources and confidence

Returns detailed information including:

• Answer text
• Confidence score
• Source references with excerpts
• Reasoning steps

pub async fn query_with_reasoning(&self, query_text: &str) -> Result<String>

Execute a query with reasoning (query decomposition)

This splits complex queries into sub-queries, gathers context for all of them, and synthesizes a comprehensive answer.

pub async fn has_documents(&self) -> bool

Check if knowledge graph has documents loaded

pub async fn has_graph(&self) -> bool

Check if knowledge graph is built

pub async fn get_stats(&self) -> Option<GraphStats>

Get knowledge graph statistics

pub async fn get_entities(&self, filter: Option<&str>) -> Result<Vec<Entity>>

Get all entities, optionally filtered

pub async fn has_knowledge_graph(&self) -> bool

Check if knowledge graph exists

pub async fn list_workspaces(&self, workspace_dir: &str) -> Result<String>

List all available workspaces

pub async fn save_workspace( &self, workspace_dir: &str, name: &str, ) -> Result<String>

Save current knowledge graph to workspace

pub async fn load_workspace( &self, workspace_dir: &str, name: &str, ) -> Result<String>

Load knowledge graph from workspace

pub async fn delete_workspace( &self, workspace_dir: &str, name: &str, ) -> Result<String>

Delete a workspace
