Usage

import asyncio

from dataclasses import field
from typing import Set, Dict

from aio_rom import Model
from aio_rom.fields import Metadata
from aio_rom.session import redis_pool


class Foo(Model):
    bar: int
    foobar: Set[int] = field(default_factory=set)
    my_boolean: bool = False
    transient_field: Dict = field(metadata=Metadata(transient=True))


class OtherFoo(Model):
    foo: Foo

async def main():
    async with redis_pool("redis://localhost"):
        foo = Foo(123, {1,2,3}, True)
        await foo.save()
        ...
        foo2 = await Foo.get(321)
        other_foo = OtherFoo(303, foo2)
        await other_foo.save()

asyncio.run(main())

2. You cannot use from __future__ import annotations in the same file you define your models. See https://bugs.python.org/issue39442
3. TODO Supported datatypes
4. Probably more ...
