Trait Attributes

pub trait Attributes {
    // Required method
    fn raw_attribute(&self, id: &str) -> Option<&Value>;

    // Provided method
    fn attribute(&self, id: &str) -> Option<&Value> { ... }
}

A node’s attributes keyed by namespaced attribute id, as in a file’s schemas (for example points::array or gltf::material).

Values are the attribute values as written, not the flattened <id>::<component> keys the upstream viewer builds. A JSON null counts as absent, because in IFCX it deletes an attribute when layers merge.

Implemented for a single [IfcxNode], a [FlatNode] from [openbim_ifcx::flatten()], a [ComposedNode] from [openbim_ifcx::compose()], plain attribute maps, and references to them.

Required Methods

fn raw_attribute(&self, id: &str) -> Option<&Value>

The raw value of attribute id, or None when absent.

Provided Methods

fn attribute(&self, id: &str) -> Option<&Value>

The value of attribute id, or None when absent or null.
