Is it possible to add derive annotations when generating Diesel models via diesel_cli_ext?

Question

I am using diesel_cli_ext to generate Rust model code:

diesel_ext --schema-file src/model/diesel/dolphin/dolphin_schema.rs --model > src/model/diesel/dolphin/dolphin_models.rs

The generated model looks like this:

#[derive(Queryable, Debug)]
pub struct AdminUser {
    pub id: i64,
    pub nickname: Option<String>,
    pub avatar_url: Option<String>,
    pub phone: Option<String>,
    pub updated_time: Option<i64>,
    pub created_time: Option<i64>,
    pub salt: Option<String>,
    pub pwd: Option<String>,
    pub sex: Option<i32>,
    pub level_type: Option<String>,
    pub phone_region: Option<String>,
    pub country_code: Option<i32>,
    pub user_status: Option<String>,
}

Is it possible to add more annotations when generating the model? I'd like to have these derives:

#[derive(Serialize, Queryable, Deserialize, Default)]

I have been adding it by myself, but the next generation overwrites the previous modifications.

Answer 1

Reading the "how to use" documentation shows that a command line option allows you to modify the derives:

    -d, --derive DERIVES
                        set struct derives

There's also an issue for per-table derive modifications.
