Struct Unit 

pub struct Unit {
    pub symbol: &'static str,
    pub dimension: Dimension,
    pub scale: Rational,
    pub offset: Rational,
}

A unit of measurement: its dimension and how to map a value in this unit to the SI base. si = value · scale + offset. Linear units have offset = 0; affine units (°C, °F) do not.

Fields

symbol: &'static str

dimension: Dimension

scale: Rational

Multiply a value in this unit by scale to reach the SI base unit. Exact, nonzero.

offset: Rational

The affine zero offset, added after scaling (0 for linear units).

Implementations

impl Unit

pub fn linear( symbol: &'static str, dimension: Dimension, scale: Rational, ) -> Unit

A linear unit (si = value · scale).

pub fn affine( symbol: &'static str, dimension: Dimension, scale: Rational, offset: Rational, ) -> Unit

An affine unit (si = value · scale + offset) — temperatures.

Trait Implementations

impl Clone for Unit

fn clone(&self) -> Unit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Unit

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

Formats the value using the given formatter.

impl PartialEq for Unit

fn eq(&self, other: &Unit) -> 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.
