Enum Quantity

}

One physical quantity.

Non-exhaustive: a match needs a wildcard arm, and code that sums or compares values should match Quantity::Simple and decide explicitly what an Quantity::Unresolved quantity means for it.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Simple

A simple measured value.

Fields

id: EntityId

The entity.

name: Option<Arc<str>>

Name, required by the schema.

description: Option<Arc<str>>

Description.

kind: QuantityKind

What it measures.

value: f64

The stated value.

unit: Option<EntityId>

The unit override, when stated.

formula: Option<Arc<str>>

Formula: how the author says it was derived. Free text.

Unresolved

A simple quantity whose value attribute holds no number: $, missing from a truncated record, or not numeric.

Kept in its place so the set still lists it; there is deliberately no value to read as 0. The same fault is reported as PropertyAnomaly::QuantityValueMissing or PropertyAnomaly::QuantityValueNotNumeric.

Fields

id: EntityId

The entity.

name: Option<Arc<str>>

Name, required by the schema.

description: Option<Arc<str>>

Description.

kind: QuantityKind

What it measures.

unit: Option<EntityId>

The unit override, when stated.

formula: Option<Arc<str>>

Formula: how the author says it was derived. Free text.

reason: UnresolvedValue

Why there is no value.

Complex

A nested group of quantities.

Fields

id: EntityId

The entity.

name: Option<Arc<str>>

Name.

discrimination: Option<Arc<str>>

Discrimination: what distinguishes the parts.

quantities: Vec<Quantity>

Contained quantities.

Unsupported

A concrete quantity type this crate does not model.

Fields

id: EntityId

The entity.

type_name: Arc<str>

Declared type, upper-cased.
