Generate plain domain models without SeaORM-specific code (Hexagonal Architecture Context) #2533

Hello,

I am currently working on a personal project to learn Rust. In this project, I am building a web application backend using SeaORM. I am trying to implement a hexagonal architecture, with two main folders: domain and infrastructure.

I’m not an expert in hexagonal architecture, but here is how I understand the responsibilities of these two parts:

In the domain folder, I only want pure business logic — completely independent of any technology used by the project. This means that anything related to SeaORM should not appear there. The goal is to isolate business logic to make testing and application evolution easier.
In the infrastructure folder, I have my database connection setup and the files generated by sea-orm-cli generate entity.

The reason for my question is the following:
When I run sea-orm-cli generate entity, I get entities that are tightly coupled with SeaORM (with traits like DeriveEntityModel, ActiveModelBehavior, and annotations like #[sea_orm(...)]).

For example, the generated code looks like this:

//! `SeaORM` Entity, @generated by sea-orm-codegen 1.1.7

use super::sea_orm_active_enums::SegmentTypeName;
use sea_orm::entity::prelude::*;

#[derive(Clone, Debug, PartialEq, DeriveEntityModel, Eq)]
#[sea_orm(table_name = "path_segment_type")]
pub struct Model {
    #[sea_orm(primary_key)]
    pub id: i32,
    pub name: Option<SegmentTypeName>,
    pub description: String
}

// Additional generated code...

impl ActiveModelBehavior for ActiveModel {}

What I would like is to automatically generate a corresponding domain file, without any SeaORM-specific code, looking something like this:

pub struct Model {
    pub id: i32,
    pub name: Option<SegmentTypeName>,
    pub description: String
}

pub enum SegmentTypeName {
    Directory,
    Lesson,
}

n other words: I’d like to generate plain Rust structures and enums matching the entities, but without SeaORM attributes or traits.

I’ve checked the documentation and couldn’t find any option or flag to achieve this.

Is there already a way to do this with SeaORM, or is there any tool/feature planned that could help with this use case?

Thank you very much for your help!
