pub trait ModelPrimaryKey<PK> {
// Required method
fn primary_key(&self) -> PK;
}Expand description
Accessor for a model’s primary key. Implemented by the macro on every
generated model struct so the batch operations can pair returned rows
back to the position of their input PK in the request, producing a
BatchItemResult with the right index and a NotFound entry for any
requested PK that didn’t come back.
