Fields

id: String

唯一 id

type_name: String

目标类型名（如 “User”）

id_mappings: Vec<Mapping>

主键字段映射（用于唯一性判断、collection 聚合）

result_mappings: Vec<Mapping>

普通字段映射

associations: Vec<NestedAssociation>

一对一嵌套映射

collections: Vec<NestedCollection>

一对多嵌套映射

discriminator: Option<Discriminator>

多态鉴别器

Implementations

impl ResultMap
