Hashing Writer

Required Methods

fn unwind_account_hashing( &self, range: RangeInclusive<u64>, ) -> Result<BTreeMap<FixedBytes<32>, Option<Account>>, ProviderError>

Unwind and clear account hashing.

Returns

Set of hashed keys of updated accounts.

fn insert_account_for_hashing( &self, accounts: impl IntoIterator<Item = (Address, Option<Account>)>, ) -> Result<BTreeMap<FixedBytes<32>, Option<Account>>, ProviderError>

Inserts all accounts into reth_db::tables::AccountsHistory table.

Returns

Set of hashed keys of updated accounts.

fn unwind_storage_hashing( &self, range: Range<BlockNumberAddress>, ) -> Result<HashMap<FixedBytes<32>, BTreeSet<FixedBytes<32>>>, ProviderError>

Unwind and clear storage hashing

Returns

Mapping of hashed keys of updated accounts to their respective updated hashed slots.

fn insert_storage_for_hashing( &self, storages: impl IntoIterator<Item = (Address, impl IntoIterator<Item = StorageEntry>)>, ) -> Result<HashMap<FixedBytes<32>, BTreeSet<FixedBytes<32>>>, ProviderError>

Iterates over storages and inserts them to hashing table.

Returns

Mapping of hashed keys of updated accounts to their respective updated hashed slots.

fn insert_hashes( &self, range: RangeInclusive<u64>, end_block_hash: FixedBytes<32>, expected_state_root: FixedBytes<32>, ) -> Result<(), ProviderError>

Calculate the hashes of all changed accounts and storages, and finally calculate the state root.

The hashes are calculated from fork_block_number + 1 to current_block_number.

The resulting state root is compared with expected_state_root.

Object Safety

This trait is not object safe.
