Struct measurements::temperature::TemperatureDelta

pub struct TemperatureDelta { /* fields omitted */ }

The TemperatureDelta struct can be used to deal with differences between temperatures in a common way.

Example

use measurements::{Temperature, TemperatureDelta};

let boiling_water = Temperature::from_celsius(100.0);
let frozen_water = Temperature::from_celsius(0.0);
let difference: TemperatureDelta = boiling_water - frozen_water;
println!("Boiling water is {} above freezing.", difference);

Trait Implementations

impl Copy for TemperatureDelta

impl Clone for TemperatureDelta

fn clone(&self) -> TemperatureDelta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TemperatureDelta

fn fmt(&self, __arg_0: &mut Formatter) -> Result

impl Measurement for TemperatureDelta

fn as_base_units(&self) -> f64

Get this quantity in the base units

fn from_base_units(kelvin_degrees: f64) -> Self

Create a new quantity from the base units

fn get_base_units_name(&self) -> &'static str

Return the base unit for this type, as a string. For example "kilograms"

fn get_appropriate_units(&self) -> (&'static str, f64)

Returns a string containing the most appropriate units for this quantity, and a floating point value representing this quantity in those units. Useful when, for example, a length might be in millimeters if it is very small, or kilometers when it is very large.

fn pick_appropriate_units(
    &self,
    list: &[(&'static str, f64)]
) -> (&'static str, f64)
