Struct ethcore::snapshot::PowRebuilder

source · [−]

pub struct PowRebuilder { /* private fields */ }

Expand description

Rebuilder for proof-of-work chains. Does basic verification for all blocks, but PoW verification for some. Blocks must be fed in-order.

The first block in every chunk is disconnected from the last block in the chunk before it, as chunks may be submitted out-of-order.

After all chunks have been submitted, we “glue” the chunks together.

Trait Implementations

source

impl Rebuilder for PowRebuilder

source

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

Feed the rebuilder an uncompressed block chunk. Returns the number of blocks fed or any errors.

source

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

Glue together any disconnected chunks and check that the chain is complete.
