## What it is
A Python library providing a Rust-like Result type (Ok/Err) for explicit error handling, fully type annotated for mypy and type checkers. The project was archived in June 2026 and is no longer maintained.

## Use cases
- return errors instead of raising exceptions in python
- rust-style result type for python
- type-safe error handling with mypy
- avoid optional tuple error returns
- pattern match on ok and err values
- railway-oriented programming in python

## When to choose
- you want explicit, type-checked error handling instead of exceptions
- your codebase already uses mypy or strict typing
- you want a small, stable, dependency-free result type

## When to avoid
- you need ongoing maintenance, bug fixes, or new Python version support
- starting a new project - consider maintained forks or alternatives
- your team prefers idiomatic Python exception handling

## Facets
- artifact type: library
- maturity: abandoned
- function: error-handling, type-system
- domain: developer-tools, programming-languages
- platform: python, cross-platform
- tags: result-type, rust-inspired, functional-programming, type-annotations, mypy, unmaintained
