result

result

Simple result type for error handling.

This module provides a basic Result type pattern for handling success and failure cases in a more explicit way than exceptions. It helps distinguish between empty data and error conditions, making the code more maintainable and debuggable.

Example usage

from journal_lib.result import Result, Success, Failure

def some_operation() -> Result[str]: if success_condition: return Success("operation result") else: return Failure("error message")

result = some_operation() if result.is_success(): print(f"Got: {result.value}") else: print(f"Error: {result.error}")

Failure

Failure(error: str)

Represents a failed operation with an error message.

Source code in packages/journal-lib/src/journal_lib/result.py

def __init__(self, error: str):
    self.error = error

Success

Success(value: Success[T])

Represents a successful operation with a value.

Source code in packages/journal-lib/src/journal_lib/result.py

def __init__(self, value: T):
    self.value = value
