Struct vapcore_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 blocks to allow in the snapshot when restoring.

Implementations

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.

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

Performs copy-assignment from source.

impl Copy for PowSnapshot

impl PartialEq<PowSnapshot> 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<'_>,
    progress: &RwLock<Progress>,
    preferred_size: usize
) -> Result<(), SnapshotError>

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

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

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

fn min_supported_version(&self) -> u64

Minimum supported snapshot version number.

fn current_version(&self) -> u64

Current version number
