Module traits 

Traits shared by relation types. Shared traits for relation types and explicit capability boundaries.

Traits

ExactSupport

Shared exact-support and materialization capability traits for add-on relation surfaces. Relation-level exact support for add-on relation surfaces.

FiniteRelation

Shared trait for finite relations. A finite relation that can report the number of stored tuples.

RelationView

Shared read-only view for deterministic exact relation iteration. A shared read-only view over a finite exact relation.

ToExactBinaryRelation

Shared exact-support and materialization capability traits for add-on relation surfaces. Materializes exact pair support as a binary relation.

ToExactNaryRelation

Shared exact-support and materialization capability traits for add-on relation surfaces. Materializes exact row support as an n-ary relation with an explicit schema.

ToExactUnaryRelation

Shared exact-support and materialization capability traits for add-on relation surfaces. Materializes exact scalar support as a unary relation.
