Implementations

impl KnowledgeCache

pub fn new() -> Self

pub fn new_with_next_id(next_id: u64) -> Self

pub fn add_entity( &mut self, name: &str, entity_type: &str, embedding_idx: i64, ) -> u64

Add an entity, returns its assigned ID.

pub fn add_relation(&mut self, src: u64, tgt: u64, relation: &str, weight: f32)

Add a relation between two entities.

pub fn get_entity(&self, id: u64) -> Option<&Entity>

Find an entity by ID.

pub fn get_relations_from(&self, src_id: u64) -> Vec<&Relation>

Find all relations where the given entity is the source.

pub fn get_relations_to(&self, tgt_id: u64) -> Vec<&Relation>

Find all relations where the given entity is the target.

pub fn add_alias(&mut self, alias: &str, entity_id: i64)

Register an alias for an entity. Case-insensitive storage.

pub fn get_aliases(&self, entity_id: i64) -> Vec<&str>

Get all aliases for a given entity.

pub fn get_entity_name(&self, entity_id: i64) -> Option<&str>

Get entity name by ID.

pub fn resolve_aliases(&self, query: &str) -> String

Resolve aliases in free text — greedy longest-match replacement.
