Transaction APIs

[kogeler]

From spec:

ext_storage_start_transaction

Start a new nested transaction. This allows to either commit or roll back all changes that are made after this call. For every transaction there must be a matching call to either ext_storage_rollback_transaction (E.1.12) or ext_storage_commit_transaction (E.1.13). This is also eective for all values manipulated using the child storage API (E.2).

ext_storage_rollback_transaction

Rollback the last transaction started by ext_storage_start_transaction (E.1.11). Any changes made during that transaction are discarded.

ext_storage_commit_transaction
Commit the last transaction started by ext_storage_start_transaction (E.1.11). Any changes made during that transaction are committed to the main state.
