Struct GraphStore 

pub struct GraphStore { /* private fields */ }

In-memory graph store backed by adjacency lists.

Implementations

impl GraphStore

pub fn new() -> Self

Creates an empty graph store.

pub fn add_entity(&mut self, entity: Entity)

Adds an entity, replacing any existing entity with the same id.

pub fn add_relation(&mut self, relation: Relation)

Adds a directed relation and updates the adjacency list.

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

Returns a reference to an entity by id.

pub fn entity_ids(&self) -> Vec<String>

Returns all entity ids.

pub fn entity_count(&self) -> usize

Returns the number of entities.

pub fn relation_count(&self) -> usize

Returns the number of relations.

pub fn neighbors(&self, entity_id: &str) -> Vec<String>

Returns the neighbor entity ids of a given entity (both directions).

pub fn subgraph(&self, seed: &str, depth: usize) -> (Vec<Entity>, Vec<Relation>)

Returns the subgraph around a seed entity: the seed, its direct neighbors, and all relations among them.

pub fn relations_for(&self, entity_id: &str) -> Vec<&Relation>

Returns all relations involving a given entity.

pub fn all_entities(&self) -> &HashMap<String, Entity>

Returns a reference to all entities.

pub fn all_relations(&self) -> &[Relation]

Returns a reference to all relations.

pub fn set_communities(&mut self, communities: Vec<Community>)

Replaces the stored communities.

pub fn communities(&self) -> &[Community]

Returns a reference to the stored communities.

pub fn set_community_summaries(&mut self, summaries: Vec<String>)

Replaces the stored community summaries.

pub fn community_summaries(&self) -> &[String]

Returns a reference to the stored community summaries.

pub fn community_summaries_mut(&mut self) -> &mut Vec<String>

Returns a mutable reference to the stored community summaries.
