Struct SnapHandoff 

pub struct SnapHandoff<N: ProviderNodeTypes> { /* private fields */ }

Hands one attempt’s downloaded state over to the staged pipeline.

Every step commits on its own and repeats safely, so an interrupted handoff runs again.

Implementations

impl<N: ProviderNodeTypes> SnapHandoff<N>

pub const fn new(factory: ProviderFactory<N>) -> Self

Creates a handoff over the node’s database.

pub fn rebuild( &self, write: SnapWrite, stop: &CancellationToken, ) -> Result<RebuildOutcome, PipelineError>

Rebuilds the trie at the pivot of write’s attempt and checks its root, abandoning the attempt on a mismatch so the next run starts a new one. Progress commits as it goes, and stop ends it early.

The attempt’s state must have been handed to the merkle stage with SnapStateVerifier::start_trie_rebuild.

pub fn hand_off( &self, write: SnapWrite, stop: &CancellationToken, ) -> Result<HandoffOutcome, PipelineError>

Publishes the state downloaded under write at its attempt’s pivot and accepts it, so the pipeline continues above the pivot. The pivot must still be canonical, and its trie is rebuilt first if Self::rebuild hasn’t finished, until stop fires.

The attempt’s state must have been handed to the merkle stage with SnapStateVerifier::start_trie_rebuild.

pub fn resume_interrupted_publish(&self) -> Result<(), PipelineError>

Publishes an attempt whose trie is rebuilt at a still canonical pivot, finishing a publish that stopped before its database commit. An attempt rebuilt but not yet handed off is published as well. Runs before the consistency check, which would otherwise unwind the static files below their anchor.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
