Struct FieldDef 

Source
pub struct FieldDef {
    pub field_type: String,
    pub required: bool,
    pub default: Option<Value>,
    pub read: Option<Vec<String>>,
    pub write: Option<Vec<String>>,
    pub fields: Option<Value>,
    pub strategy: Option<String>,

    pub metric: Option<String>,
}

Fields§

§field_type: String§required: bool§default: Option<Value>§read: Option<Vec<String>>§write: Option<Vec<String>>§fields: Option<Value>

嵌套 object 字段的原始定义(未规范化,与 JS 保持一致)

§strategy: Option<String>

ID 供给策略(阶段2):仅 _id 字段有意义 —— "autoincrement" = 数据库自增列 赋值(SQL 后端),宿主不生成、core 不注入 _id;Mongo 后端无自增语义, 执行器对此显式报错(AUTOINCREMENT_NOT_SUPPORTED)。其余值非法(注册期校验)。

§dim: Option<u32>

向量维度:field_type == "vector" 时必填,正整数(VR-01)

§metric: Option<String>

向量距离度量:cosine / l2 / ip,缺省 cosine(仅 vector 字段允许出现)

Implementations§
