Struct LayerRelationship 

pub struct LayerRelationship { /* private fields */ }

Relationship to another layer or table in the service.

ESRI Documentation

Source: https://developers.arcgis.com/rest/services-reference/enterprise/layer-feature-service/

Each layer or table can participate in one or more relationship classes. The relationships array in a layer definition lists the relationships that this layer participates in.

Example from ESRI

Implementations

impl LayerRelationship

Auto-generated by derive_getters::Getters.

pub fn id(&self) -> &i32

Relationship class ID (unique within service).

pub fn name(&self) -> &Option<String>

Relationship class name.

pub fn role(&self) -> &RelationshipRole

Role of this layer in the relationship.

pub fn cardinality(&self) -> &RelationshipCardinality

Cardinality of the relationship.

pub fn related_table_id(&self) -> &i32

ID of the related layer or table.

pub fn key_field(&self) -> &String

Key field name on this layer (foreign or primary key).

pub fn composite_key_field_name(&self) -> &Option<String>

Composite key field name (for composite key relationships).

Trait Implementations

impl Clone for LayerRelationship

fn clone(&self) -> LayerRelationship

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayerRelationship

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

Formats the value using the given formatter.

impl Default for LayerRelationship

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LayerRelationship

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LayerRelationship

fn eq(&self, other: &LayerRelationship) -> 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 Serialize for LayerRelationship

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for LayerRelationship
