导入 rust mod 时在 `super` 中找不到 `schema`

我正在学习 rust，现在尝试导入一个结构，这是源文件路径app_root/src/model/response/playlist_response.rs，我正在导入另一个这样的结构：

#[path = "../../models.rs"]
mod models;

use models::QueryPlaylist;

该model.rs路径是app_root/src/models.rs，该models.rs文件是这样的：

use super::schema::posts;
use super::schema::playing_record;
use super::schema::favorites;
use super::schema::songs;
use super::schema::playlist;
use super::schema::album;
use rocket::serde::Serialize;

#[derive(Insertable,Serialize,Queryable)]
#[table_name="playlist"]
pub struct QueryPlaylist {
    pub id: i64,
    pub creator: i64,
    pub name: String,
    pub cover_url: Option<String>,
    pub description: Option<String>,
    pub subscribed: Option<i32>,
    pub subscribed_count: Option<i64>,
    pub comment_count: Option<i64>,
    pub share_count: Option<i32>,
    pub play_count: Option<i32>
}

当我编译项目时，显示如下错误：

$ cargo build                                                                                                                                        ‹ruby-2.7.2›

该schema.rs文件路径app_root/src/schema.rs。我使用错误的方式导入？这样的问题是什么？我该怎么做才能让它发挥作用？这是main.rs：

#[macro_use]
extern crate rocket;

#[macro_use]
extern crate diesel;

// #[macro_use]
// extern crate redis;

#[path="biz/music/music.rs"] mod music;
#[path="config/db/config.rs"] mod config;
#[path="biz/music/songs.rs"] mod songs;
#[path="biz/music/test.rs"] mod test;
#[path="biz/user/user.rs"] mod user;
#[path="biz/music/playlist.rs"] mod playlist;


#[launch]
fn rocket() -> _ {
    rocket::build()
        .mount("/music/music", routes![music::play_record,music::save_play_record,music::like,music::dislike])
        .mount("/music/songs",routes![songs::detail])
        .mount("/music/user",routes![user::recent_found])
        .mount("/music/playlist",routes![playlist::user_playlist])
