isos is a Python library that introduces Option and Result types to implement the "result pattern" in your code.
In traditional Python, errors are handled with exceptions. The result pattern takes a different approach by treating errors as values that can be:
- Passed between functions
- Transformed
- Chained together
- Explicitly handled at the appropriate point
This forces developers to consciously handle non-existent values and error conditions, leading to more robust and predictable code.
- Option Type: Explicitly represents the presence or absence of a value
- Result Type: Represents either a successful value or an error value
- Custom Errors: Create your own error types by subclassing the
Errorclass
By making errors first-class citizens in your code, isos helps prevent bugs that might occur from unhandled edge cases and makes your error handling strategy more transparent and systematic.
