Struct PersistentStorageSession 

pub struct PersistentStorageSession {
    pub catalog: Arc<dyn CatalogFacade>,
    pub backend: Arc<dyn PersistentStorageBackend>,
}

Session-bound catalog and physical storage handles created together.

Both handles must share the same transaction context. Keeping their construction behind one provider prevents a catalog write from escaping through a different connection or transaction than document/index writes.

Fields

catalog: Arc<dyn CatalogFacade>

backend: Arc<dyn PersistentStorageBackend>

Implementations

impl PersistentStorageSession

pub fn new( catalog: Arc<dyn CatalogFacade>, backend: Arc<dyn PersistentStorageBackend>, ) -> Self

pub fn validate_transaction_affinity(&self) -> StorageBackendResult<()>

Check the transaction model, database incarnation and session affinity before restoration, migration or attachment. Versioned pairs require a matching reported affinity and backend write cancellation; serialized pairs may omit both capabilities.
