History Writer

Required Methods

fn unwind_account_history_indices<'a>( &self, changesets: impl Iterator<Item = &'a (BlockNumber, AccountBeforeTx)>, ) -> ProviderResult<usize>

Unwind and clear account history indices.

Returns number of changesets walked.

fn unwind_account_history_indices_range( &self, range: impl RangeBounds<BlockNumber>, ) -> ProviderResult<usize>

Unwind and clear account history indices in a given block range.

Returns number of changesets walked.

fn insert_account_history_index( &self, index_updates: impl IntoIterator<Item = (Address, impl IntoIterator<Item = u64>)>, ) -> ProviderResult<()>

Insert account change index to database. Used inside AccountHistoryIndex stage

fn unwind_storage_history_indices( &self, changesets: impl Iterator<Item = (BlockNumberAddress, StorageEntry)>, ) -> ProviderResult<usize>

Unwind and clear storage history indices.

Returns number of changesets walked.

fn unwind_storage_history_indices_range( &self, range: impl RangeBounds<BlockNumberAddress>, ) -> ProviderResult<usize>

Unwind and clear storage history indices in a given block range.

Returns number of changesets walked.

fn insert_storage_history_index( &self, storage_transitions: impl IntoIterator<Item = ((Address, B256), impl IntoIterator<Item = u64>)>, ) -> ProviderResult<()>

Insert storage change index to database. Used inside StorageHistoryIndex stage

fn update_history_indices( &self, range: RangeInclusive<BlockNumber>, ) -> ProviderResult<()>

Read account/storage changesets and update account/storage history indices.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
