Struct Unit 

pub struct Unit {
    pub dimension: Dimension,
    pub scale: f64,
    pub offset: f64,
}

A unit: its dimension and the affine map to the coherent SI unit of that dimension, value_in_si = value · scale + offset.

Fields

dimension: Dimension

The physical dimension.

scale: f64

Size of one unit in coherent SI units (> 0).

offset: f64

SI value of the unit’s zero (0 except for scales such as Cel).

Implementations

impl Unit

pub fn convert_to(&self, value: f64, to: &Unit) -> Result<f64, UnitError>

A reading value in this unit, in to.

Errors

UnitError::NotFinite for value, UnitError::DimensionMismatch when to measures something else.

pub fn difference_to(&self, value: f64, to: &Unit) -> Result<f64, UnitError>

An amount of change value in this unit, in to (offsets cancel).

Errors

As Unit::convert_to.
