You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: integration.rs
    path of file: ./repos/rivet/svc/pkg/kv/ops/get/tests
    
    the code of the file until where you have to start completion: use chirp_worker::prelude::*;
use proto::backend::pkg::*;

use serde_json::json;

#[worker_test]
async fn empty(ctx: TestCtx) {
	let namespace_id = Uuid::new_v4();
	let namespace_id2 = Uuid::new_v4();
	let value = serde_json::to_vec(&json!({ "foo": "bar" })).unwrap();
	let key = "test/key";

	let msg_res = msg!([ctx] kv::msg::write(namespace_id, key) -> kv::msg::update {
		namespace_id: Some(namespace_id.into()),
		key: key.into()
    
async fn empty(ctx: TestCtx) {

	})
	.await
	.unwrap();

	assert_eq!(

	);
	assert_eq!(msg_res.key, key, "wrong key");
