Struct ethcore::snapshot::PowSnapshot

pub struct PowSnapshot {
    pub blocks: u64,
    pub max_restore_blocks: u64,
}

Snapshot creation and restoration for PoW chains. This includes blocks from the head of the chain as a loose assurance that the chain is valid.

Fields

blocks: u64

Number of blocks from the head of the chain to include in the snapshot.

max_restore_blocks: u64

Number of to allow in the snapshot when restoring.

Methods

impl PowSnapshot

pub fn new(blocks: u64, max_restore_blocks: u64) -> PowSnapshot

Create a new instance.

Trait Implementations

impl Clone for PowSnapshot

fn clone(&self) -> PowSnapshot

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for PowSnapshot

impl PartialEq for PowSnapshot

fn eq(&self, other: &PowSnapshot) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &PowSnapshot) -> bool

This method tests for !=.

impl SnapshotComponents for PowSnapshot

fn chunk_all(     &mut self,     chain: &BlockChain,     block_at: H256,     chunk_sink: &mut ChunkSink,     preferred_size: usize ) -> Result<(), Error>

Create secondary snapshot chunks; these corroborate the state data in the state chunks.

fn rebuilder(     &self,     chain: BlockChain,     db: Arc<BlockChainDB>,     manifest: &ManifestData ) -> Result<Box<Rebuilder>, Error>

Create a rebuilder, which will have chunks fed into it in aribtrary order and then be finalized.

fn min_supported_version(&self) -> u64

Minimum supported snapshot version number.

fn current_version(&self) -> u64

Current version number
