Struct exonum_merkledb::RocksDB

pub struct RocksDB { /* fields omitted */ }

Database implementation on top of RocksDB backend.

RocksDB is an embedded database for key-value data, which is optimized for fast storage. This structure is required to potentially adapt the interface to use different databases.

Methods

impl RocksDB

pub fn open<P: AsRef<Path>>(path: P, options: &DbOptions) -> Result<Self>

Opens a database stored at the specified path with the specified options.

If the database does not exist at the indicated path and the option create_if_missing is switched on in DbOptions, a new database will be created at the indicated path.

pub fn create_checkpoint<T: AsRef<Path>>(&self, path: T) -> Result<()>

Creates checkpoint of this database in the given directory. See RocksDB docs for details.

Successfully created checkpoint can be opened using RocksDB::open.
