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 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.

Trait Implementations

impl Clone for RelationshipSelectionRequest

fn clone(&self) -> RelationshipSelectionRequest

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RelationshipSelectionRequest

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Ord for RelationshipSelectionRequest

fn cmp(&self, other: &RelationshipSelectionRequest) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RelationshipSelectionRequest

fn eq(&self, other: &RelationshipSelectionRequest) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for RelationshipSelectionRequest

fn partial_cmp(&self, other: &RelationshipSelectionRequest) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
