Struct LpgStore 

pub struct LpgStore { /* private fields */ }

The main LPG graph store.

This is the core storage for labeled property graphs, providing efficient node/edge storage and adjacency indexing.

Implementations

impl LpgStore

pub fn new() -> Self

Creates a new LPG store with default configuration.

pub fn with_config(config: LpgStoreConfig) -> Self

Creates a new LPG store with custom configuration.

pub fn current_epoch(&self) -> EpochId

Returns the current epoch.

pub fn new_epoch(&self) -> EpochId

Creates a new epoch.

pub fn create_node(&self, labels: &[&str]) -> NodeId

Creates a new node with the given labels.

pub fn create_node_with_props( &self, labels: &[&str], properties: impl IntoIterator<Item = (impl Into<PropertyKey>, impl Into<Value>)>, ) -> NodeId

Creates a new node with labels and properties.

pub fn get_node(&self, id: NodeId) -> Option<Node>

Gets a node by ID.

pub fn delete_node(&self, id: NodeId) -> bool

Deletes a node and all its edges.

pub fn node_count(&self) -> usize

pub fn get_edge(&self, id: EdgeId) -> Option<Edge>

Gets an edge by ID.

pub fn delete_edge(&self, id: EdgeId) -> bool

Deletes an edge.

pub fn edge_count(&self) -> usize

Returns the number of edges.

pub fn neighbors( &self, node: NodeId, direction: Direction, ) -> impl Iterator<Item = NodeId> + '_

Returns an iterator over neighbors of a node.

pub fn nodes_by_label(&self, label: &str) -> Vec<NodeId>

Returns nodes with a specific label.
