Enum ColumnarProjectionSourceV1 

pub enum ColumnarProjectionSourceV1 {
    Scalar {
        lineage: ContractLineage,
        definition_fingerprint: DefinitionFingerprint,
    },
    Vector(VectorProjectionSourceV1),
}

One canonical schema-bound scalar or vector source identity.

Variants

Scalar

Scalar columnar state bound to the accepted physical definition fingerprint.

Fields

lineage: ContractLineage

Contract lineage owning the schema.

definition_fingerprint: DefinitionFingerprint

Accepted legacy definition fingerprint.

Vector(VectorProjectionSourceV1)

Vector columnar state retaining the accepted lineage/entity/field tuple.
