"""
Represents the outcome of a workflow/job/task or any operation, along with associated metadata.
This class supports nesting of results to represent tasks with sub-tasks, and includes
various attributes to track status, timing, files, and links.
Attributes:
name (str): The name of the task.
status (str): The current status of the task. Should be one of the values defined in the Status class.
start_time (Optional[float]): The start time of the task in Unix timestamp format. None if not started.
duration (Optional[float]): The duration of the task in seconds. None if not completed.
results (List[Result]): A list of sub-results representing nested tasks.
files (List[str]): A list of file paths or names related to the result.
links (List[str]): A list of URLs related to the result (e.g., links to reports or resources).
info (str): Additional information about the result. Free-form text.
Inner Class:
Status: Defines possible statuses for the task, such as "success", "failure", etc.
