Implementations

impl ReadSnapshot

pub fn open_nodes(&self, names: &[String]) -> KnowledgeGraphOut

Open named entities + incident relations.

pub fn read_graph(&self) -> KnowledgeGraphOut

Full graph read. Returns all entities and relations.

pub fn search_entities(&self, query: &str) -> Result<Vec<Entity>>

Search entities by keyword.

pub fn get_entity(&self, name: &str) -> Option<Entity>

Get a single entity by name.

pub fn neighbors( &self, name: &str, direction: Direction, rtype: Option<&str>, depth: u32, ) -> Result<KnowledgeGraphOut>

Neighborhood expansion (same logic as KnowledgeGraph::neighbors but read-only).

pub fn describe_entity(&self, name: &str) -> Result<Value>

Describe an entity: entity details, incident relations, neighbors, degree.

pub fn find_path(&self, from: &str, to: &str) -> Result<Vec<String>>

Find the shortest path between two entities.

pub fn extract_subgraph( &self, names: &[String], depth: u32, ) -> Result<KnowledgeGraphOut>

Extract a subgraph around the given entities.

pub fn batch_get_entities(&self, names: &[String]) -> Vec<Option<Entity>>

Batch get entities.

pub fn graph_stats(&self) -> Value

Graph statistics.

pub fn search_relations( &self, from: Option<&str>, to: Option<&str>, rtype: Option<&str>, ) -> Vec<Relation>

Search relations by from/to/type filters.

pub fn entity_type_counts(&self) -> Vec<(String, usize)>

Count entities per type.

pub fn relation_type_counts(&self) -> Vec<(String, usize)>

Count relations per type.

pub fn export(&self, format: &str) -> Result<String>

Export the graph in one of: json, mermaid, dot.

pub fn find_all_paths( &self, from: &str, to: &str, max_depth: usize, max_paths: usize, ) -> Result<Vec<Vec<String>>>

Find all paths between two entities.
