StepState<Input, Output> class

Immutable state of a single step execution that holds all execution details.

Key features:

  • Input/output data tracking
  • Execution timing
  • Error information
  • Status tracking

Example:

final state = StepState(
  step: ValidationStep(),
  input: requestData,
  status: StepStatus.completed,
  startTime: DateTime.now(),
);

if (state.isSuccess) {
  print('Duration: ${state.duration}');
}

Constructors

StepState({required ChainStep<Input, Output> step, required Input input, Output? output, required StepStatus status, required DateTime startTime, DateTime? endTime, Object? error})
