transacts |
This effect indicates that any actions performed by the function can be rolled back. The transacts effect is required any time a mutable variable (var) is written. You'll be notified when you compile your code if the transacts effect was added to a function that can't be rolled back. Note that this check is not done for functions with the native specifier. |
