Struct NodeValueUpdate 

pub struct NodeValueUpdate {
    pub value: Value,
    pub access_mode: String,
    pub min: Option<f64>,
    pub max: Option<f64>,
    pub inc: Option<f64>,
}

Live node value update published by the service on change.

min, max, and inc are optional runtime constraint hints. When present, the UI can tighten slider ranges without re-parsing XML. Services that do not implement constraint propagation may omit them.

Legacy payload. New code should publish FeatureState instead — it carries the same information plus runtime introspection (access mode, kind, implementation/availability, available enum entries). NodeValueUpdate stays in the wire contract so older services/clients keep working.

Fields

value: Value

access_mode: String

min: Option<f64>

Optional minimum allowed value for this node at the current camera state.

max: Option<f64>

Optional maximum allowed value for this node at the current camera state.

inc: Option<f64>

Optional increment (step) for this node’s value.
