pub struct RelationEntry<'a, F: Clone, EF: RelationEFTraitBound<F>, R: Relation<F, EF>> { /* private fields */ }Expand description
A struct representing a relation entry.
relation is the relation into which elements are entered.
multiplicity is the multiplicity of the elements.
A positive multiplicity is used to signify a “use”, while a negative multiplicity
signifies a “yield”.
values are elements in the base field that are entered into the relation.
