Rust Diesel не строится с ошибкой при использовании необъявленного ящика или модуля

Я пытаюсь создать свое первое приложение Rust с поддержкой базы данных, я использую Diesel с SQLite, всякий раз, когда я создаю свое приложение, я получаю следующее сообщение об ошибке:

My schema.rs:

joinable!(document -> category (category_id));
joinable!(document -> correspondent (correspondent_id));
joinable!(document -> doctype (doc_type_id));

allow_tables_to_appear_in_same_query!(
    category,
    correspondent,
    doctype,
    document,
);

и наконец мой main.rs:

mod models;
fn main() {

    println!("Hello, world!");
}

Я попытался добавить use schema::* к своему model.rs, но безуспешно, так как модель не нашлась. Я также попробовал это решение Безуспешно.

Я не могу использовать правильные прицелы, я новичок в ржавчине, я все еще привыкаю к ​​ее парадигме
