A KVStore implementation that writes to and reads from an SQLite database.

Implementations

impl SqliteStore

pub fn new( data_dir: PathBuf, db_file_name: Option<String>, kv_table_name: Option<String>, ) -> Result<Self>

Constructs a new SqliteStore.

If not already existing, a new SQLite database will be created in the given data_dir under the given db_file_name (or the default to DEFAULT_SQLITE_DB_FILE_NAME if set to None).

pub fn get_data_dir(&self) -> PathBuf

Returns the data directory.
