Where to find the database..

Variants

Auto

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.

Fields of Auto

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.

RocksDb

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

Fields of RocksDb

path: PathBuf

Path to the database.

cache_size: usize

Cache size in MiB.

ParityDb

Load a ParityDb database from a given path.

Fields of ParityDb

path: PathBuf

Path to the database.

Custom(Arc<dyn Database<H256> + 'static>)

Use a custom already-open database.

Tuple Fields of Custom

0: Arc<dyn Database<H256> + 'static>
