Struct ProjectUnits 

pub struct ProjectUnits { /* private fields */ }

The set of units a file declares in its IfcUnitAssignment, keyed by unit-type token ("LENGTHUNIT", "VOLUMETRICFLOWRATEUNIT", …). Only the unit-types the file actually declares are present; anything else falls back to the IFC-canonical SI default in ProjectUnits::unit_for_measure.

Implementations

impl ProjectUnits

pub fn resolve(decoder: &mut EntityDecoder<'_>, project_id: u32) -> Self

Resolve the full unit assignment reachable from project_id. Never fails: an absent / malformed assignment yields an empty table (all measures then fall back to their SI default symbols).

pub fn unit_for_measure(&self, measure_type: &str) -> Option<ResolvedUnit>

The display unit for a property/quantity whose IFC measure value type is measure_type (e.g. "IfcVolumetricFlowRateMeasure"). Prefers the file’s declared unit for the measure’s unit-type and otherwise falls back to the IFC-canonical SI default. Returns None for dimensionless measures (ratios, counts) and non-measure value types (labels, …).

pub fn resolved_for_unit_type(&self, unit_type: &str) -> Option<&ResolvedUnit>

The resolved unit the file declares for a raw unit-type token, if any.

pub fn monetary(&self) -> Option<&ResolvedUnit>

The resolved monetary (currency) unit, if the file declares one.

pub fn declared_len(&self) -> usize

Number of declared unit-types (excluding monetary). Test/telemetry aid.
