Expand description

Where to find the database..

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<H256> + 'static>

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.
