Struct SQLiteKeyValueStorage 

pub struct SQLiteKeyValueStorage { /* private fields */ }

Shared SQLite KeyValue storage handle with catalog and backend factories.

Implementations

impl SQLiteKeyValueStorage

pub fn open(path: &Path) -> SQLiteResult<Self>

pub fn open_in_memory() -> SQLiteResult<Self>

pub fn from_connection(conn: ManagedConnection) -> SQLiteResult<Self>

pub fn store(&self) -> Arc<SQLiteKeyValueStore>

pub fn catalog(&self) -> SQLiteKeyValueCatalog

pub fn backend(&self) -> SQLiteKeyValueStorageBackend

Trait Implementations

impl Clone for SQLiteKeyValueStorage

fn clone(&self) -> SQLiteKeyValueStorage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PersistentStorageProvider for SQLiteKeyValueStorage

fn open_session(&self) -> StorageBackendResult<PersistentStorageSession>

fn storage_identity( &self, ) -> StorageBackendResult<Option<PersistentStorageIdentity>>

Return the database identity shared by every session this provider opens. Custom providers that cannot expose a stable identity may keep the default; engines built from the same Arc provider still share an in-process coordinator.

fn open_initial_session( &self, ) -> Result<PersistentStorageSession, StorageBackendError>

Open handles for initial Engine restoration. Providers may defer catalog schema preparation until CatalogFacade::initialize_storage runs inside the owning transaction; ordinary session factories must return an initialized catalog.

fn auxiliary_encryption_key(&self) -> Option<StorageEncryptionKey>

Protect engine-owned auxiliary files with the database’s encryption credential. Encrypted file providers must forward this capability; None declares that their auxiliary storage may be unencrypted.
