Expand description
Additional operations (only some) database transactions expose, on top of
IDatabaseTransactionOpsCore
In certain contexts exposing these operations would be a problem, so they are moved to a separate trait.
Required Methods§
sourcefn set_tx_savepoint<'life0, 'async_trait>(
&'life0 mut self,
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
fn set_tx_savepoint<'life0, 'async_trait>(
&'life0 mut self,
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
Create a savepoint during the transaction that can be rolled back to using rollback_tx_to_savepoint. Rolling back to the savepoint will atomically remove the writes that were applied since the savepoint was created.
Warning: Avoid using this in fedimint client code as not all database transaction implementations will support setting a savepoint during a transaction.
