Client database

Implementations

impl<Block, StorageBackend> ClientDatabase<Block, StorageBackend>

where Block: GenericOwnedBlock, StorageBackend: ClientDatabaseStorageBackend,

pub async fn open<GBB>( options: ClientDatabaseOptions<GBB, StorageBackend>, ) -> Result<Self, ClientDatabaseError>

where GBB: FnOnce() -> GenesisBlockBuilderResult<Block>,
