abslstatusStatus

abslstatusStatus is a concept found within Google's Abseil C++ library, specifically in the absl::Status class. It represents a result that can either be successful or indicate an error. The Status class itself is a lightweight, value-semantic object that encapsulates a status code and an optional error message.

The abslstatusStatus can be thought of as a structured way to handle and propagate errors in C++ code. Instead of relying solely on return codes or exceptions for error handling, absl::Status allows functions to return a Status object that clearly communicates whether an operation succeeded or failed. If an operation fails, the Status object will contain an error code and a descriptive message explaining the issue.

Commonly, functions that might encounter errors will return an absl::Status. If the function is successful, it will return absl::OkStatus(), a predefined constant indicating success. Otherwise, it will return a Status object populated with an appropriate error code and message. This approach promotes more explicit and robust error handling by making the success or failure of an operation a first-class citizen in the function's return type. Developers can then check the returned Status object to determine the outcome and react accordingly.
