Struct CriterionDescriptor 

pub struct CriterionDescriptor {
    pub key: &'static str,
    pub label: &'static str,
    pub help: &'static str,
    pub quantity: Option<&'static str>,
    pub kind: CriterionKind,
}

Descriptor of one criterion in an engine’s criteria catalog (spec §7.2).

key is stable per engine: applications persist valuations against it, so renaming one is a compatibility break.

Fields

key: &'static str

Stable criterion identifier, unique within the engine.

label: &'static str

Human-facing name.

help: &'static str

One or two sentences on what the criterion judges.

quantity: Option<&'static str>

§5 quantity key — values are in the quantity’s SI display unit — or None for a dimensionless criterion.

kind: CriterionKind

Shape of the criterion’s value.
