strongtyping-pyoverload

Runtime method overloading for Python

strongtyping-pyoverload provides a powerful overload decorator that brings true runtime method overloading to Python, similar to C++.

Key Features

• Native Pydantic Integration: Automatically validate and dispatch based on Pydantic models.
• Deep Inheritance & Mixin Support: Respects Method Resolution Order (MRO) for complex class hierarchies.
• AI-Ready Metadata: Sets __signature__ and __annotations__ for better IDE and AI assistant support.
• High Performance: Optimized lookup logic with caching for minimal overhead.
• Modern Python: Full support for typing.Annotated, keyword-only parameters, and Python 3.13+.

Quick Start

from strongtyping_pyoverload import overload

class DataProcessor:
    @overload
    def process(self, data: str):
        return data.upper()

    @overload
    def process(self, data: list):
        return [item * 2 for item in data]
