fun <T> Datastore.transactional(options: TransactionOptions, block: Datastore.() -> T): T
Run a function, with all contained datastore operations transactional.
WARNING: currently if there are any async operations in the transaction,
and you don't .await() them in the transaction, whether they
participate in the transaction or not is undefined behavior.
TODO(colin): we can probably do something clever with coroutine scopes
to force ourselves to wait on them automatically.
Note that clients must only use these extension methods for transactions, and they must not construct a transaction in any other way.
fun <T> Datastore.transactional(block: Datastore.() -> T): T
