Enum RelationConstraint 

pub enum RelationConstraint {
    OwnersOf(Vec<String>),
    NotOwnersOf(Vec<String>),
}

Which reverse-join read a constraint on a Relation-typed field asks for.

reduceInRelation (DatabaseController.js:1050-1143). Note the fourth case: any other constraint on a relation field yields no results at all, because upstream falls into its else branch with an empty related-id list. That is reproduced rather than turned into an error, since it narrows rather than broadens and a client can already observe it.

Variants

OwnersOf(Vec<String>)

The owning objects related to any of these ids.

NotOwnersOf(Vec<String>)

The complement: objectId $nin.
