Struct RelationshipSelectionRequest 

pub struct RelationshipSelectionRequest { /* private fields */ }

Request for relationship-selected objects within a caller-bound universe.

Implementations

impl RelationshipSelectionRequest

pub fn try_new( anchor: ObjectId, candidate_universe: Vec<ObjectId>, query: RelationshipQuery, ) -> Result<Self, RelationshipSelectionError>

Creates a request with a canonical, duplicate-free candidate universe.

pub fn with_absent_ends(self, policy: AbsentEndPolicy) -> Self

Sets how instances with an absent required end are treated.

pub fn absent_ends(&self) -> AbsentEndPolicy

How instances with an absent required end are treated.

pub fn anchor(&self) -> &ObjectId

Anchor whose relationships determine the selection.

pub fn candidate_universe(&self) -> &[ObjectId]

Complete caller-approved universe from which candidates may be returned.

pub fn query(&self) -> &RelationshipQuery

Requested relationship operation.
