Struct SqlitePrimitiveStorage 

pub struct SqlitePrimitiveStorage { /* private fields */ }

SQLite-based primitive storage implementation.

Uses a single table for persistent storage with a connection protected by Mutex.

Implementations

impl SqlitePrimitiveStorage

pub fn new(config: SqliteConfig) -> Self

Create a new SQLite primitive storage with the given configuration.

pub fn in_memory() -> Self

Create an in-memory SQLite storage for testing.

Trait Implementations

impl Clone for SqlitePrimitiveStorage

fn clone(&self) -> SqlitePrimitiveStorage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl TierStorage for SqlitePrimitiveStorage

fn get(&self, key: &[u8]) -> Result<Option<CowVec<u8>>>

Get the value for a key, or None if not found.

fn contains(&self, key: &[u8]) -> Result<bool>

Check if a key exists in storage.

fn set(&self, entries: Vec<(CowVec<u8>, Option<CowVec<u8>>)>) -> Result<()>

fn range_rev_next( &self, cursor: &mut RangeCursor, start: Bound<&[u8]>, end: Bound<&[u8]>, batch_size: usize, ) -> Result<RangeBatch>

Fetch the next batch of entries in reverse key order (ascending).

fn ensure_table(&self) -> Result<()>

Ensure storage is initialized.

fn clear_table(&self) -> Result<()>
