Leviathan is an ultra-fast event loop for Python's asyncio framework, designed to enhance the performance of asynchronous programming by leveraging the power of Zig. As a drop-in replacement for the default event loop, Leviathan ensures seamless compatibility with existing Python projects while delivering optimized performance.

Features

• Ultra-Fast Speed: Boosted by low-level optimizations from Zig, Leviathan significantly reduces latency and enhances execution speed for async operations.
• Full Asyncio Compatibility: Easily integrates into current asyncio-based applications, allowing for a smooth transition to a more efficient event loop without extensive code modifications.
• Efficient Design: Focuses on maximizing performance with minimal overhead, making it an excellent choice for high-performance applications.
• Simplicity: Designed for easy installation and straightforward usage, making it accessible for developers of all levels.

Basic Usage

Leviathan can be used simply by replacing the default event loop in your asyncio code. Here’s a brief example:

from leviathan import Loop
import asyncio

async def main():
    print("Hello from Leviathan!")
    await asyncio.sleep(1)
    print("Goodbye from Leviathan!")

loop = Loop()
try:
    loop.run_until_complete(main())
finally:
    loop.close()
