abslStatus

abslstatus is a Python library that provides a robust and standardized way to represent and handle errors. It is part of Google's Abseil Python library collection. The core of abslstatus is the Status object, which encapsulates both the outcome of an operation (success or failure) and an associated error message or details. This allows for more explicit and structured error handling compared to traditional exception-based approaches in some scenarios.

The Status object has two primary states: OK and non-OK. An OK status indicates that an operation completed successfully. A non-OK status signifies an error and typically includes a status code (e.g., `abslstatus.StatusCode.NOT_FOUND`, `abslstatus.StatusCode.INVALID_ARGUMENT`) and a detailed message. It can also carry auxiliary data, such as a stack trace or custom error payloads, providing richer context for debugging and error resolution.

Developers can use abslstatus to create functions that return Status objects instead of raising exceptions. This can be beneficial in situations where errors are expected to occur frequently and need to be handled in a non-disruptive manner, or when propagating errors across different layers of an application without the overhead of exception handling. The library also offers utilities for converting between Status objects and standard Python exceptions, providing flexibility in how errors are managed. By promoting a consistent error reporting mechanism, abslstatus aims to improve code clarity and maintainability.
