pub fn feed(&mut self, chunk: &[u8], flag: &AtomicBool) -> Result<(), Error>

Feed an uncompressed state chunk into the rebuilder.

pub fn finalize(self, era: u64, id: H256) -> Result<Box<JournalDB>, Error>

Finalize the restoration. Check for accounts missing code and make a dummy journal entry. Once all chunks have been fed, there should be nothing missing.

pub fn state_root(&self) -> H256

Get the state root of the rebuilder.
