When inserting data in batches, it is desired to return the number of successfully inserted data

    pub async fn insert_batch(db: &DbConn, list: &Vec<RoleMenuMergeSaveDTO>) -> Result<u64, DbErr> {
        let result: Vec<role_menu_merge::ActiveModel> = list.iter().map(|item| role_menu_merge::ActiveModel {
            menu_id: Set(item.menu_id),
            role_id: Set(item.role_id),
            create_time: Set(Option::from(chrono::Local::now().naive_local().to_owned())),
            update_time: Set(Option::from(chrono::Local::now().naive_local().to_owned())),
            ..Default::default()
        }).collect();
        let insert_result = RoleMenuMerge::insert_many(result)
            .exec(db)
            .await?;
        Ok(insert_result.last_insert_id)
    }

For example, in the above code, I want to return the number of successfully inserted entries, but it seems that it cannot be implemented at the moment. Can we add a method similar to rows_affected?

Start at the insert_many(...).exec(db) entry point and inspect the execution result used by the example. Compare it with any existing rows_affected behavior; done means batch insertion can expose the number of successfully inserted entries while preserving last_insert_id behavior, with coverage for the new result.
