J'essaie de créer ma première application Rust avec un support de base de données, j'utilise Diesel avec SQLite, chaque fois que je construis mon application, j'obtiens le message d'erreur suivant :

et enfin mon main.rs
:
mod models;
fn main() {
println!("Hello, world!");
}
J'ai essayé d'ajouter use schema::*
à mon model.rs
sans succès car le modèle n'est pas trouvé. J'ai également essayé cette solution sans succès.
Je n'arrive pas à utiliser les bonnes lunettes de visée, je suis nouveau dans la rouille, je m'habitue encore à son paradigme.
