Struct Thing 

pub struct Thing {
    pub thing_id: ThingId,
    pub policy_id: Option<PolicyId>,
    pub attributes: BTreeMap<SmolStr, Value>,
    pub features: BTreeMap<FeatureId, Feature>,
}

A Thing — the top-level digital twin.

Fields

thing_id: ThingId

Globally unique id, namespace:name.

policy_id: Option<PolicyId>

Optional access policy reference.

attributes: BTreeMap<SmolStr, Value>

Free-form attributes (manufacturer, location, …).

features: BTreeMap<FeatureId, Feature>

Features by id.

Implementations

impl Thing

pub fn new(thing_id: ThingId) -> Self

Construct an empty Thing — only the id is required.

pub fn with_feature(self, id: FeatureId, feature: Feature) -> Self

Insert or replace a feature.

pub fn feature(&self, id: &FeatureId) -> Option<&Feature>

Borrow a feature by id.

pub fn feature_mut_or_default(&mut self, id: FeatureId) -> &mut Feature

Mutably borrow a feature by id, creating it if absent.
