Storage ChangeSet reader

Required Methods

fn storage_changeset( &self, block_number: u64, ) -> Result<Vec<(BlockNumberAddress, StorageEntry)>, ProviderError>

Iterate over storage changesets and return the storage state from before this block.

fn get_storage_before_block( &self, block_number: u64, address: Address, storage_key: FixedBytes<32>, ) -> Result<Option<StorageEntry>, ProviderError>

Search the block’s changesets for the given address and storage key, and return the result.

Returns None if the storage slot was not changed in this block.

fn storage_changesets_range( &self, range: RangeInclusive<u64>, ) -> Result<Vec<(BlockNumberAddress, StorageEntry)>, ProviderError>

Get all storage changesets in a range of blocks.

NOTE: Get inclusive range of blocks.

fn storage_changeset_count(&self) -> Result<usize, ProviderError>

Get the total count of all storage changes.

Provided Methods

fn storage_block_changeset( &self, block_number: u64, ) -> Result<Vec<StorageBeforeTx>, ProviderError>

Get storage changesets for a block as static-file rows.

Default implementation uses storage_changeset and maps to StorageBeforeTx.
