- Workflow:
- No limit to the complexity of a directed acyclic graph.
- Single input and single output.
- Canceled at any time during execution.
- Shipped with any loggers.
- Transit:
- TransitInterface: Allow custom transits.
- Any inputs and outputs(except the initial input and final output).
- The worker accepts the incoming context parameter and allows receiving
Done()signal. - Any worker error will terminate the execution and notify all the loggers to record events, including
panic()and recover from it.
- Logger:
- LoggerInterface: Allow custom loggers.
- Predefined four log levels.
- Default logger: Log events are output to the standard output and standard error.
- Error collector: Collect errors generated during workflow execution.
