Struct SqliteStorage 

pub struct SqliteStorage { /* private fields */ }

SQLite-backed implementation of ContextStorage.

Implementations

impl SqliteStorage

pub fn open(db_path: &Path, max_entries: usize) -> Result<Self>

Open (or create) a SQLite database at db_path and run migrations.

For ":memory:", a single-connection pool is used so that all operations share the same in-memory database instance.

Errors

Returns an error if the database cannot be opened, the connection pool cannot be built, or migrations fail.

pub fn pool(&self) -> Arc<Pool<SqliteConnectionManager>>

Return a reference-counted handle to the connection pool so that SqliteSearcher can share it.

pub fn schema_version(&self) -> Result<i64>

Return the current schema version from the database.

Errors

Returns an error if the connection pool or query fails.

pub fn checkpoint(&self) -> Result<()>

Run a WAL checkpoint (TRUNCATE mode) to flush the WAL file.

Safe to call at any time; no-op if no WAL pages are pending.

Errors

Returns an error if the connection pool or checkpoint pragma fails.
