Error Handling

TODO: Elaborate

• Error Handling
  • 3 ways to handle errors
    • Set a main output to none: Happens when the node is unable to generate this output (e.g. when inputs are not available or there was a temporary error inside of the node)
      • Recoverable, expected to be resolved in the next cycle
    • Return Err(...) from cycle()
      • Unrecoverable, but framework is allowed to shutdown gracefully, expected that it will not improve in the next cycles/in the future
    • Panic with e.g. panic!() or by unwrap()ing
      • Unrecoverable, immediate shutdown, kernel will take down the whole process, there is no way to gracefully shutdown
