Struct AccountRangeDownload 

Source 
pub struct AccountRangeDownload<C, F> { /* private fields */ }
Expand description

Downloads the account ranges an attempt still needs, one at a time in key order.

Self::next fetches the range at the coverage cursor the store records; the caller resolves its storage and code, then Self::commit persists everything and moves the cursor.

Implementations§

Source§

impl<C, F> AccountRangeDownload<C, F>

Source

pub const fn new(client: C, factory: F, runtime: Runtime) -> Self

Creates a download that continues from the coverage the store records.

Source

pub const fn with_response_bytes(self, response_bytes: u64) -> Self

Returns this download asking peers for at most response_bytes per response.

Source

pub const fn coverage(&self) -> Option<AccountCoverage>

How far the download has got, as last read from the store.

Source§

impl<C, F> AccountRangeDownload<C, F>
where C: SnapClient + Clone + Unpin, F: DatabaseProviderFactory + Clone + 'static, F::Provider: MetadataProvider, F::ProviderRW: BlockHashReader + MetadataProvider + MetadataWriter + StateWriter + DBProvider<Tx: DbTxMut>,

Source

pub async fn next(&mut self) -> Result<Option<AccountRangeStep>, SnapSyncError>

Fetches the range at the coverage cursor.

Ok(None) once every account is downloaded. A failed request leaves the cursor where it was, so the download can be resumed from the persisted coverage.

Source

pub async fn commit( &mut self, verified: VerifiedRange, storages: B256Map<HashedStorage>, bytecodes: Vec<(B256, Bytecode)>, ) -> Result<AccountCoverage, SnapSyncError>

Commits verified with the storage and code resolved for it, moving the cursor past it.

Refused, with the coverage unchanged, when the attempt no longer accepts the write the range was fetched under or a dependency is missing.

Source

pub async fn next_repair( &mut self, ) -> Result<Option<AccountRangeStep>, SnapSyncError>

Fetches the first account scheduled for repair on its own, proved at the pivot.

Ok(None) once nothing is scheduled.

Source

pub async fn commit_repair( &mut self, verified: VerifiedRange, slots: Vec<(B256, U256)>, ) -> Result<usize, SnapSyncError>

Commits the account verified repairs with the pivot’s values of slots, returning how many accounts remain scheduled.
