1. Rename all your data files to only contains struct name. For example, rename "model.user.User" to "User".
2. Replace attribute #[arthas] with #[derive(Default, Debug, Clone, PartialEq, Serialize, Deserialize, Arthas)]
3. If you use attribute value like #[arthas(one)], replace with the attribute #[arthas(is_one)]
4. If you use the rename attribute like #[arthas_rename("from = to")], replace with the attribute #[arthas(rename = "from = to")]
5. If you use both #[arthas(one)] and #[arthas_rename("from = to")], replace with #[arthas(is_one, rename = "from = to")]
