#[derive(Clone)]
struct Payload {}

impl Expiry for Payload {
    fn valid(&self) -> bool {
        true
    }
}

impl Provider<Payload> for MyProvider {
    fn update(&self) -> ExpiryFut<Payload> {
        future::ok::<Payload, ExpiryGetError>(Payload {}).into_future().boxed()
    }
}


let rs = RemoteStore::new(MyProvider {});
let payload = block_on(rs.get());
