Struct ContainedSpec 

pub struct ContainedSpec {
    pub name: String,
    pub host_column: String,
    pub kind: ContainedKind,
    pub columns: Vec<Column>,
    pub id_column: Option<String>,
}

Schema for a contained relation — records embedded in a column of the parent row rather than stored in a separate table.

Unlike Reference (which names a foreign-key column), a contained relation names the host column holding the embedded data, carries the contained record’s own column schema, and an optional id column. With no id column, contained-many records are addressed by positional index.

Fields

name: String

host_column: String

Column on the parent row holding the embedded object (one) or array of objects (many).

kind: ContainedKind

ContainsOne or ContainsMany.

columns: Vec<Column>

Columns of the contained record.

id_column: Option<String>

Field used as the contained record’s id. None → positional index (contained-many) or the fixed relation name (contained-one).
