Struct PathIndex 

pub struct PathIndex { /* private fields */ }

Fixed-label-sequence reachability. Durable clones copy only a handle. Queries return owned results and can report storage errors.

Implementations

impl PathIndex

pub fn build<G: GraphStore>( store: &G, graph: &str, sequences: &[Vec<String>], ) -> GraphStoreResult<Self>

pub fn open_persistent( catalog: Arc<dyn CatalogFacade>, backend: Arc<dyn PersistentStorageBackend>, key: &str, graph: &str, sequences: &[Vec<String>], ) -> GraphStoreResult<Self>

Bind a durable definition without reading any entity or reachability row.

pub fn build_persistent( catalog: Arc<dyn CatalogFacade>, backend: Arc<dyn PersistentStorageBackend>, key: &str, graph: &str, sequences: &[Vec<String>], ) -> GraphStoreResult<Self>

Build in bounded batches in one storage checkpoint. A failure preserves both the old definition and its materialization.

pub fn rebind_persistent( &self, catalog: Arc<dyn CatalogFacade>, backend: Arc<dyn PersistentStorageBackend>, ) -> GraphStoreResult<Self>

Rebind only the physical session, never copy the index’s data.

pub fn with_graph_read_view(&self, store: Arc<GraphStoreHandle>) -> Self

Bind a transaction/cursor view whose own-write overlay cannot use reachability pages from the live storage transaction. Only requested sequences are evaluated; no resident index or graph is constructed.

pub fn lookup( &self, sequence: &[String], ) -> GraphStoreResult<Option<BTreeSet<(u64, u64)>>>

pub fn has_path(&self, sequence: &[String]) -> bool

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