aiorate 1.0.0

Loop frequency regulator for asyncio.

aiorate

Loop frequency regulator for asyncio with an API similar to rospy.Rate.

Installation

pip install aiorate

Usage

The Rate class provides a non-blocking loop frequency limiter:

• Set the loop frequency in Hz at construction: rate = aiorate.Rate(200.0)
• Call await rate.sleep() at every loop cycle

Example

import asyncio
import aiorate

async def main():
    rate = aiorate.Rate(400.0)  # Hz
    while True:
        loop_time = asyncio.get_event_loop().time()
        print(f"Hello from loop at {loop_time:.3f} s")
        await rate.sleep()

if __name__ == "__main__":
    asyncio.run(main())
