Implementations

impl RocksDb

pub fn open_cf<P: AsRef<Path>>(
    path: P,
    num_cfs: u32
) -> Result<Self, StorageError>

Opens storage from the given path with its given names. If storage does not exists, it creates a new storage file at the given path with its given names, and opens it. If RocksDB fails to open, returns StorageError.

pub fn open_secondary_cf<P: AsRef<Path> + Clone>(
    primary_path: P,
    secondary_path: P,
    num_cfs: u32
) -> Result<Self, StorageError>

Opens a secondary storage instance from the given path with its given names. If RocksDB fails to open, returns StorageError.
