Struct ExactUnit 

#[non_exhaustive]
pub struct ExactUnit {
    pub unit: Option<EntityId>,
    pub from_project: bool,
    pub dimensions: [i32; 7],
    pub scale: f64,
    pub offset: f64,
}

A measure’s effective unit, resolved to SI base units.

value_si = value * scale + offset.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

unit: Option<EntityId>

The unit entity that applies, or None for a dimensionless measure (IFCCOUNTMEASURE, IFCRATIOMEASURE, …) that takes no unit.

from_project: bool

Whether unit is the project default rather than an explicit unit.

dimensions: [i32; 7]

SI dimensional exponents [L, M, T, I, Θ, N, J].

scale: f64

Multiplier into the SI base unit (kilogram for mass, kelvin for temperature, radian for plane angle).

offset: f64

Added after scaling; nonzero only for DEGREE_CELSIUS.
