Trait ethcore::snapshot::Rebuilder

pub trait Rebuilder: Send {
    fn feed(
        &mut self, 
        chunk: &[u8], 
        engine: &dyn EthEngine, 
        abort_flag: &AtomicBool
    ) -> Result<(), Error>;
    fn finalize(&mut self, engine: &dyn EthEngine) -> Result<(), Error>;
}

Restore from secondary snapshot chunks.

Required methods

fn feed(
    &mut self,
    chunk: &[u8],
    engine: &dyn EthEngine,
    abort_flag: &AtomicBool
) -> Result<(), Error>

Feed a chunk, potentially out of order.

Check abort_flag periodically while doing heavy work. If set to false, should bail with Error::RestorationAborted.

fn finalize(&mut self, engine: &dyn EthEngine) -> Result<(), Error>

Finalize the restoration. Will be done after all chunks have been fed successfully.

This should apply the necessary “glue” between chunks, and verify against the restored state.
