在os.rs中,该类型被用作占位符,表示对于SGX环境中的路径操作,暂不支持。 JoinPathsError:该结构体表示路径拼接错误,用于在路径拼接失败时提供错误信息。 Env:该结构体提供了对环境变量的读取和操作的功能。它可以获取环境变量的值,迭代所有环境变量的键值对,并提供一些其他的环境变量操作方法。 EnvStrDebug<'a>:这...

连接表的join语句 link_id 字段的rust类型的对应连接字段 例如,如某结构体User 其中某一字段定义为:user_type:UserType,设置link_id="id" 写入User表记录时,会自动读取self.user_type.id为对应数据库字段的值 link_id_type 连接字段的rust类型 如以上UserType::id为u32类型,则link_id_type="u32" ...
