pub struct RelationshipResolver { /* private fields */ }

Resolver — index over relationships per source object.

Implementations

impl RelationshipResolver

pub fn new() -> Self

Constructor.

pub fn add(&mut self, rel: Relationship)

Add a relationship.

pub fn outgoing(&self, source: &ObjectId) -> Vec<&Relationship>

List of relationships originating from a source.

pub fn len(&self) -> usize

Number of stored relationships (including inverse ones for Bi).

pub fn is_empty(&self) -> bool

true if there are no relationships.

pub fn cascade_targets_for_delete(&self, source: &ObjectId) -> Vec<ObjectId>

Spec §B.5.4 — cascading targets for a source ID when the source object is deleted.

pub fn cascade_targets_for_update(&self, source: &ObjectId) -> Vec<ObjectId>

Trait Implementations

impl Clone for RelationshipResolver

fn clone(&self) -> RelationshipResolver

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelationshipResolver

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

Formats the value using the given formatter.

impl Default for RelationshipResolver

fn default() -> RelationshipResolver

Returns the “default value” for a type.

impl Eq for RelationshipResolver

impl PartialEq for RelationshipResolver

fn eq(&self, other: &RelationshipResolver) -> 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.
