TypeScript

import { queries } from "./module_bindings";
conn.subscriptionBuilder().subscribe([queries.user.build()]);

C#

conn.SubscriptionBuilder().AddQuery(ctx => ctx.From.User().Build()).Subscribe();

Rust

conn.subscription_builder().add_query(|ctx| ctx.from.user().build()).subscribe();

NOTE: We would like to remove the .build() for 2.0, but you can try it out with the existing API.
