Struct ElementKind 

pub struct ElementKind {
    pub id: &'static str,
    pub label: &'static str,
    pub label_plural: &'static str,
    pub class: ElementClass,
    pub role: Option<ElementRole>,
    pub badge: &'static str,
}

Descriptor of one element kind in an engine’s catalog (spec §4.2).

The catalog is static and model-free, like the block catalog: an application must be able to build its chrome — tables, filters, layer toggles, legends — before any model is loaded. id follows the block-id stability rule: removing one, or changing the meaning of one, is a break on the order of a file-format break.

Fields

id: &'static str

Stable kind identifier, opaque to this layer.

label: &'static str

Human-facing singular name.

label_plural: &'static str

Human-facing plural name.

class: ElementClass

The kind’s element class.

role: Option<ElementRole>

What the kind does in the network (spec §4.3), or None for a kind that is not in the flow network at all — a rain gage conveys nothing, and a curve or a control rule is not in it to begin with.

badge: &'static str

One- or two-character glyph for dense UI (markers, chips).
