SnapGeneration

Struct SnapGeneration 

Source
pub struct SnapGeneration { /* private fields */ }
Expand description

One attempt at downloading state, anchored to the pivot block it targets.

The anchor is kept as both a number-hash pair and a state root: the hash decides whether the attempt is still on the canonical chain, and the root is what downloaded ranges authenticate against.

Implementations§

Source§

impl SnapGeneration

Source

pub const fn new(target: BlockNumHash, state_root: B256) -> Self

Creates a generation anchored to the given pivot, before any range is downloaded.

Source

pub const fn target(&self) -> BlockNumHash

Pivot block this generation is anchored to.

Source

pub const fn state_root(&self) -> B256

State root that downloaded ranges authenticate against.

Source

pub const fn phase(&self) -> SnapPhase

Stage this generation has reached.

Source

pub const fn lag(&self, head: u64) -> u64

Returns how far the canonical head has moved past this generation’s anchor.

Source

pub fn is_canonical( &self, provider: &impl HeaderProvider, ) -> Result<bool, SnapSyncError>

Returns whether the block this generation is anchored to is still canonical.

Separate from whether it is worth finishing: an orphaned anchor is recoverable from the abandoned branch’s lists.
