C<transaction> takes a coderef that will be executed in the context of a |
33
|
|
|
|
|
|
|
transaction. If an error is thrown, the transaction will rollback. If the code |
34
|
|
|
|
|
|
|
executes successfully, the transaction will be committed. There is no support |
35
|
|
|
|
|
|
|
for nested transactions, nested calls to C<transaction> will simply be subsumed |
36
|
|
|
|
|
|
|
by their parent transaction. |
