History Writer

Required Methods

fn unwind_account_history_indices<'a>( &self, changesets: impl Iterator<Item = &'a (u64, AccountBeforeTx)>, ) -> Result<usize, ProviderError>

Unwind and clear account history indices.

Returns number of changesets walked.

fn unwind_account_history_indices_range( &self, range: impl RangeBounds<u64>, ) -> Result<usize, ProviderError>

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>)>, ) -> Result<(), ProviderError>

Insert account change index to database. Used inside AccountHistoryIndex stage

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

Unwind and clear storage history indices.

Returns number of changesets walked.

fn unwind_storage_history_indices_range( &self, range: impl RangeBounds<u64>, ) -> Result<usize, ProviderError>

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, FixedBytes<32>), impl IntoIterator<Item = u64>)>, ) -> Result<(), ProviderError>

Insert storage change index to database. Used inside StorageHistoryIndex stage

fn update_history_indices( &self, range: RangeInclusive<u64>, ) -> Result<(), ProviderError>

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".
