Enum MeasureUnit 

pub enum MeasureUnit {
    Typed {
        unit_type: &'static str,
        default_symbol: &'static str,
    },
    Monetary,
    Dimensionless,
}

How a measure maps onto the file’s declared units.

Variants

Typed

A named or derived unit-type token (matches IfcUnitEnum / IfcDerivedUnitEnum), with the IFC-canonical SI symbol shown when the file declares no unit for that type.

Fields

unit_type: &'static str

Unit-type token, e.g. "VOLUMETRICFLOWRATEUNIT", "LENGTHUNIT".

default_symbol: &'static str

SI default symbol, e.g. "m\u{00B3}/s", "mm" never appears here (prefixes are file-declared); base SI only.

Monetary

The value is a monetary amount; the symbol comes from IfcMonetaryUnit.

Dimensionless

Dimensionless / unit-less (ratios, counts, descriptive, …). No symbol.

Trait Implementations

impl Clone for MeasureUnit

fn clone(&self) -> MeasureUnit

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MeasureUnit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MeasureUnit

fn eq(&self, other: &MeasureUnit) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
