Struct VariableDescriptor 

pub struct VariableDescriptor {
    pub id: &'static str,
    pub label: &'static str,
    pub symbol: Option<&'static str>,
    pub quantity: Option<&'static str>,
    pub ramp: RampHint,
}

Descriptor of one result variable in an engine’s per-class catalog (spec §6.1).

id follows the block-id stability rule — application preferences and saved views may reference it.

Fields

id: &'static str

Stable variable identifier, opaque to this layer.

label: &'static str

Human-facing name.

symbol: Option<&'static str>

Compact engine-authored notation (≤3 chars) for space-starved surfaces — ideally the domain’s standard symbol (spec §6.1) — or None for the application’s own fallback.

quantity: Option<&'static str>

Key of the quantity the values carry (spec §5), or None for dimensionless variables.

ramp: RampHint

How values map to a colour scale.
