Expand description
A storage changes structure that can be generated by the data collected in OverlayedChanges
.
This contains all the changes to the storage and transactions to apply theses changes to the backend.
Fields§
§main_storage_changes: StorageCollection
All changes to the main storage.
A value of None
means that it was deleted.
child_storage_changes: ChildStorageCollection
All changes to the child storages.
offchain_storage_changes: OffchainChangesCollection
Offchain state changes to write to the offchain database.
transaction: BackendTransaction<H>
A transaction for the backend that contains all changes from
main_storage_changes
and from
child_storage_changes
.
offchain_storage_changes
.
transaction_storage_root: H::Out
The storage root after applying the transaction.
transaction_index_changes: Vec<IndexOperation>
Changes to the transaction index,
