Variants§

§

Auto

Fields

§paritydb_path: PathBuf

Path to the paritydb database.

§rocksdb_path: PathBuf

Path to the rocksdb database.

§cache_size: usize

Cache size in MiB. Used only by RocksDb variant of DatabaseSource.

Check given path, and see if there is an existing database there. If it’s either RocksDb or ParityDb, use it. If there is none, create a new instance of ParityDb.

§

RocksDb

Fields

§path: PathBuf

Path to the database.

§cache_size: usize

Cache size in MiB.

Load a RocksDB database from a given path. Recommended for most uses.

§

ParityDb

Fields

§path: PathBuf

Path to the database.

Load a ParityDb database from a given path.

§

Custom

Fields

§db: Arc<dyn Database<DbHash>>

the handle to the custom storage

§require_create_flag: bool

if set, the create flag will be required to open such datasource

Use a custom already-open database.
