Struct ResourceInstance 

pub struct ResourceInstance { /* private fields */ }

Represents a physical instance of a resource at a specific entity location.

Instances capture the “WHERE” of resources - they represent specific physical instances of resources located at particular entities.

Examples

use sea_core::primitives::{Entity, Resource, ResourceInstance};
use sea_core::units::unit_from_string;

let warehouse = Entity::new_with_namespace("Warehouse A".to_string(), "default".to_string());
let product = Resource::new_with_namespace("Camera", unit_from_string("units"), "default".to_string());

let camera_123 = ResourceInstance::new(
    product.id().clone(),
    warehouse.id().clone()
);

assert_eq!(camera_123.entity_id(), warehouse.id());

Implementations

impl ResourceInstance

pub fn new(resource_id: ConceptId, entity_id: ConceptId) -> Self

Creates a new ResourceInstance (default namespace).

pub fn new_with_namespace( resource_id: ConceptId, entity_id: ConceptId, namespace: impl Into<String>, ) -> Self

pub fn id(&self) -> &ConceptId

pub fn resource_id(&self) -> &ConceptId

pub fn entity_id(&self) -> &ConceptId

pub fn namespace(&self) -> &str

pub fn set_attribute(&mut self, key: impl Into<String>, value: Value)

pub fn get_attribute(&self, key: &str) -> Option<&Value>

pub fn attributes(&self) -> &HashMap<String, Value>

Returns all attributes as a reference.

Trait Implementations

impl Clone for ResourceInstance

fn clone(&self) -> ResourceInstance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResourceInstance

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ResourceInstance

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ResourceInstance

fn eq(&self, other: &ResourceInstance) -> 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 ResourceInstance

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
