parameters to calculate accounts hash

Fields

use_bg_thread_pool: bool

true to use a thread pool dedicated to bg operations

check_hash: bool

verify every hash in append vec/write cache with a recalculated hash this option will be removed

ancestors: Option<&'a Ancestors>

‘ancestors’ is used to get storages and also used if ‘use_write_cache’ is true to get account data from the write cache

use_write_cache: bool

does hash calc need to consider account data that exists in the write cache? if so, ‘ancestors’ will be used for this purpose as well as storages.

epoch_schedule: &'a EpochSchedule

rent_collector: &'a RentCollector

store_detailed_debug_info_on_failure: bool

used for tracking down hash mismatches after the fact

full_snapshot: Option<FullSnapshotAccountsHashInfo>

Some if this is an incremental snapshot which only hashes slots since the base full snapshot

disable_rehash_for_rent_epoch: bool

temporarily here for feature activation #28934
