example

• integrates with dataclasses and pydantic as a side effect

A definition of a data model. Can be either shared globally or reimplemented separately. Also defines an async loop function that will be used to produce Data objects.

from dataclasses import dataclass
import asyncio
import random
from uuid import uuid4
from dataplace import ModelIO, Controller


@dataclass(slots=True, frozen=True)
class Data(ModelIO):
    id: str
    value: int


async def produce(controller: Controller) -> None:
    while controller.running:
        await controller.async_hold()
        await controller.async_callback(
            Data(id=str(uuid4()), value=random.randint(0, 9))
        )

        await asyncio.sleep(1)
