Struct PrimaryKey 

pub struct PrimaryKey {
    pub fields: Vec<FieldId>,
    pub index: IndexId,
}

The primary key definition for a root model.

A primary key consists of one or more fields that uniquely identify a record, plus a reference to the backing Index.

Examples

use toasty_core::schema::app::{PrimaryKey, IndexId, ModelId};

let pk = PrimaryKey {
    fields: vec![ModelId(0).field(0)],
    index: IndexId { model: ModelId(0), index: 0 },
};
assert_eq!(pk.fields.len(), 1);

Fields

fields: Vec<FieldId>

The fields that compose this primary key, in order.

index: IndexId
