Struct BaseUnit 

pub struct BaseUnit {
    pub name: &'static str,
    pub symbol: &'static str,
    pub aliases: &'static [&'static str],
    pub dimension: Dimension,
    pub scale: f64,
    pub offset: f64,
}

An irreducible base unit like meter, second, or kilogram.

Fields

name: &'static str

Primary name (e.g., “meter”)

symbol: &'static str

Short symbol (e.g., “m”)

aliases: &'static [&'static str]

Alternative names/aliases

dimension: Dimension

The dimension this unit represents

scale: f64

Scale relative to the canonical SI base unit (1.0 for SI base units)

offset: f64

Additive offset for converting to SI: SI = (value + offset) * scale. Zero for most units. Celsius has offset 273.15 (K = °C + 273.15).

Implementations

impl BaseUnit

pub const fn new( name: &'static str, symbol: &'static str, aliases: &'static [&'static str], dimension: Dimension, scale: f64, ) -> Self

Create a new base unit.

pub const fn with_offset( name: &'static str, symbol: &'static str, aliases: &'static [&'static str], dimension: Dimension, scale: f64, offset: f64, ) -> Self

Create a new base unit with an additive offset. Offset units use affine conversion via their scale and offset.

impl BaseUnit

pub const fn dimension(&self) -> Dimension

Get the dimension of this unit.

pub fn pow(&self, exp: impl Into<Rational16>) -> Unit

Raise this unit to a power, returning a Unit.
