Enum UnitScale 

pub enum UnitScale {
    Literal(RationalInteger),
    Unresolved {
        written: String,
        segments: Vec<String>,
        name: String,
    },
    Reference(ReferenceTarget),
}

Conversion factor of a measure unit: a plan-time rational, or a data/rule reference whose value is known only during evaluation.

Variants

Literal(RationalInteger)

1 of this unit equals this many canonical units.

Unresolved

Written path before graph resolution (rate, fx.rate). Replaced by Self::Reference when the declaring spec’s scales are resolved.

Fields

written: String

segments: Vec<String>

name: String

Reference(ReferenceTarget)

Resolved number data field or rule. After planning succeeds every dynamic unit is this variant — never Self::Unresolved.
