Functions

builder_drop_rolls_back

TransactionBuilder auto-rolls back on drop just like a regular transaction.

builder_on_connection_commit

TransactionBuilder from Connection commits data like a regular transaction.

builder_on_db_commit

TransactionBuilder from Db commits data like a regular transaction.

builder_with_all_options

TransactionBuilder with both isolation and read_only sends both options.

builder_with_isolation_level

TransactionBuilder with isolation level sends the correct option to the driver.

builder_with_read_only

TransactionBuilder with read_only sends the correct option to the driver.

cancel_queued_commit_keeps_connection_reusable

Cancelling a queued commit keeps the connection reusable.

commit_failure_rolls_back_before_connection_reuse

A failed commit rolls back before the connection returns to the pool.

commit_persists_data

Data created inside a committed transaction is visible afterwards.

delete_rolled_back

Deletes inside a rolled-back transaction are discarded.

driver_sees_begin_commit

Verify the driver receives BEGIN, statements, and COMMIT in the right order.

driver_sees_begin_rollback

Verify the driver receives BEGIN and ROLLBACK when rolled back.

drop_without_finalize_rolls_back

Dropping a transaction without commit or rollback automatically rolls back.

multi_op_inside_tx_uses_savepoints

When a multi-op statement (e.g. create with association) runs inside an interactive transaction, the engine wraps it in SAVEPOINT/RELEASE instead of BEGIN/COMMIT.

multiple_ops_in_transaction

Multiple operations inside a single transaction are all committed together.

nested_commit_both

A committed nested transaction (savepoint) persists when the outer transaction also commits.

nested_driver_sees_rollback_to_savepoint

Verify the driver log when a nested transaction is rolled back shows ROLLBACK TO SAVEPOINT.

nested_driver_sees_savepoint_ops

Verify the driver log for a nested transaction shows SAVEPOINT / RELEASE SAVEPOINT around the inner work.

nested_drop_rolls_back_savepoint

Dropping a nested transaction without finalize rolls back just that savepoint.

nested_rollback_inner

Rolling back a nested transaction discards only its changes; the outer transaction can still commit its own.

nested_rollback_outer

Rolling back the outer transaction discards everything, including changes from an already-committed nested transaction.

read_your_writes

Read-your-writes: data created inside a transaction is visible within it before commit.

rollback_discards_data

Data created inside a rolled-back transaction is not visible.

rollback_failure_retries_before_connection_reuse

A failed rollback is retried before the connection returns to the pool.

transaction_via_dyn_executor

Calling .transaction() through &mut dyn Executor works.

two_sequential_nested_transactions

Two sequential nested transactions: first committed, second rolled back. Only data from the first survives.

update_inside_transaction

Updates inside a transaction are committed.

update_rolled_back

Updates inside a rolled-back transaction are discarded.
