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: update.rs
    path of file: ./repos/crates.io/src/tests/routes/users
    
    the code of the file until where you have to start completion: use crate::util::{RequestHelper, Response, TestApp};
use http::StatusCode;

pub trait MockEmailHelper: RequestHelper {
    // TODO: I don't like the name 
    
fn test_other_users_cannot_change_my_email() {
    let (app, anon, user) = TestApp::init().with_user();
    let another_user = app.db_new_user("not_me");
    let another_user_model = another_user.as_model();

    let response = user.update_email_more_control(
        another_user_model.id,
        Some("pineapple@pineapples.pineapple"),
    );
    assert_eq!(response.status(), StatusCode::BAD_REQUEST);
    assert_eq!(
        response.json(),
        json!({ "errors": [{ "detail": "current user does not match requested user" }] })
    );

    let response = anon.update_email_more_control(
        another_user_model.id,
        Some("pineapple@pineapples.pineapple"),
    );
    assert_eq!(response.status(), StatusCode::FORBIDDEN);
    assert_eq!(
        response.json(),
        json!({ "errors": [{ "detail": "must be logged in to perform that action" }] })
    );
}
