Struct Instance 

pub struct Instance { /* private fields */ }

Represents a concrete instance of an Entity with specific field values.

Instances allow defining specific data objects in the DSL that can be referenced in policies and flows.

Examples

use sea_core::primitives::Instance;
use serde_json::json;

let mut vendor = Instance::new_with_namespace("vendor_123", "Vendor", "default");
vendor.set_field("name", json!("Acme Corp"));
vendor.set_field("credit_limit", json!(50000));

assert_eq!(vendor.entity_type(), "Vendor");
assert_eq!(vendor.get_field("name"), Some(&json!("Acme Corp")));

Implementations

impl Instance

pub fn new(name: impl Into<String>, entity_type: impl Into<String>) -> Self

Creates a new Instance (default namespace).

pub fn new_with_namespace( name: impl Into<String>, entity_type: impl Into<String>, namespace: impl Into<String>, ) -> Self

pub fn id(&self) -> &ConceptId

pub fn name(&self) -> &str

pub fn entity_type(&self) -> &str

pub fn namespace(&self) -> &str

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

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

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

Returns all fields as a reference.

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

Returns a mutable reference to fields for bulk updates.

Trait Implementations

impl Clone for Instance

fn clone(&self) -> Instance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Instance

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Instance

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Instance

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
