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

&self,
range: impl RangeBounds<BlockNumberAddress>,
) -> Result<usize, ProviderError>
fn unwind_storage_history_indices_range( &self, range: impl RangeBounds<BlockNumberAddress>, ) -> Result<usize, ProviderError>
Unwind and clear storage history indices in a given block range.
Returns number of changesets walked.
fn insert_storage_history_index(

Insert storage change index to database. Used inside StorageHistoryIndex stage
fn update_history_indices(
&self,
range: RangeInclusive<u64>,
) -> Result<(), ProviderError>
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", so this trait is not object safe.
