Document an example of async usage?

I’m not an expert in the python ecosystem, and am not sure what’s required from me to support asynchronous resolvers in an Ariadne schema. If it’s possible, I’d love a brief example illustrating a working async resolver!

---

What I’ve tried so far (using python 3.7):

from aiodataloader import DataLoader
from ariadne import ResolverMap, gql, start_simple_server

# DATA LOADERS
heroesLoader = HeroesLoader()

class HeroesLoader(DataLoader):
    async def batch_load_fn(self, keys):
        # return await batch_get_heroes()

# SCHEMA DEFINITION
type_defs = gql("""
type Query {
    heroes: [Hero!]!
}

type Hero {
    name: String!
    shortName: String
    title: String
}
""")

# RESOLVERS
query = ResolverMap("Query")
hero = ResolverMap("Hero")

@query.field("heroes")
async def resolve_heroes(*_):
    return await heroesLoader.load('_')

start_simple_server(type_defs, [query, hero])
