Features

• Fully asynchronous API compatible with Python 3.10+.
• Deterministic AIMD core with slow start, congestion avoidance, and fast recovery.
• Designed for integration inside asyncio-based services and SDKs.
• 100% test coverage.

Usage Example

import asyncio

from aimd_limiter import AIMDAsyncLimiter


async def main() -> None:
    limiter = AIMDAsyncLimiter(max_rate=20.0)
    async with limiter.acquire():
        # Perform work guarded by AIMD flow control.
        ...


asyncio.run(main())
