Start a redis docker image if you don't already have it running locally:
    docker run --rm --name async-kash-redis-example -p 6379:6379 -d redis
Set the required env variable and run this example and run with required features:
    KASH_REDIS_CONNECTION_STRING=redis://127.0.0.1:6379 cargo run --example redis-async --features "async redis_store redis_tokio"
Cleanup the redis docker container:
    docker rm -f async-kash-redis-example
