Trait ActiveRecord 

pub trait ActiveRecord:
    Model
    + ModelExt
    + RelationLoader
    + Clone
    + Send
    + Sync {
    // Provided methods
    fn with(self, relation: &str) -> WithRelation<Self> { ... }
    fn with_all(self, relations: Vec<&str>) -> WithRelation<Self> { ... }
}

支持关系加载的模型 trait（ActiveRecord 模式）

L-5 修复：补充示例文档

示例

use sz_orm_core::model::{Model, ActiveRecord};

#[derive(Debug, Clone, Default)]
struct User { id: i64, name: String }

impl Model for User {
    type PrimaryKey = i64;
    fn table_name() -> &'static str { "users" }
    fn pk(&self) -> Self::PrimaryKey { self.id }
    fn set_pk(&mut self, pk: Self::PrimaryKey) { self.id = pk; }
}

// 假设已实现 ModelExt + RelationLoader
impl ActiveRecord for User {}

// 通过 with() 链式预加载多个关系
let user = User { id: 1, name: "Alice".into() }
    .with("orders")
    .with("profile");

Provided Methods

fn with(self, relation: &str) -> WithRelation<Self>

预加载指定关系 用法：user.with("orders").with("profile").load(&mut conn).await

fn with_all(self, relations: Vec<&str>) -> WithRelation<Self>

一次性预加载多个关系

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
