Struct soroban_simulation_zephyr::AutoRestoringSnapshotSource

pub struct AutoRestoringSnapshotSource<T: SnapshotSourceWithArchive> { /* private fields */ }

The SnapshotSource implementation that automatically restores the archived ledger entries accessed during get calls.

This does not define a concrete implementation for ledger lookups and just wraps a SnapshotSourceWithArchive.

The restored entries will have the rent automatically bumped to min_persistent_entry_ttl, which is consistent with the behavior of RestoreFootprintOp if it was called in the same ledger.

Implementations

impl<T: SnapshotSourceWithArchive> AutoRestoringSnapshotSource<T>

pub fn new( snapshot_source: Rc<T>, ledger_info: &LedgerInfo, ) -> Result<Self, Error>

pub fn reset_restored_keys(&self)

Resets all the restored keys recorded so far.

pub fn simulate_restore_keys_op( &self, network_config: &NetworkConfig, adjustment_config: &SimulationAdjustmentConfig, ledger_info: &LedgerInfo, ) -> Result<Option<RestoreOpSimulationResult>>

Simulates a RestoreFootprintOp for all the keys that have been restored so far.

Trait Implementations

impl<T: SnapshotSourceWithArchive> SnapshotSource for AutoRestoringSnapshotSource<T>

fn get( &self, key: &Rc<LedgerKey>, ) -> Result<Option<EntryWithLiveUntil>, HostError>

Returns the ledger entry for the key and its live_until ledger if entry exists, or None otherwise.
