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: Transaction

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,
