Implementations

impl StateRebuilder

pub fn new(db: Arc<dyn KeyValueDB>, pruning: Algorithm) -> Self

Create a new state rebuilder to write into the given backing DB.

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

Feed an uncompressed state chunk into the rebuilder.

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

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.
