Struct measurements::angle::Angle

pub struct Angle { /* fields omitted */ }

The 'Angle' struct can be used to deal with angles in a common way.

Example

use measurements::Angle;

let whole_cake = Angle::from_degrees(360.0);
let pieces = 6.0;
let slice = whole_cake / pieces;
println!("Each slice will be {} degrees", slice.as_degrees());

Trait Implementations

impl Copy for Angle

impl Clone for Angle

fn clone(&self) -> Angle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Angle

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

impl Measurement for Angle

fn as_base_units(&self) -> f64

Get this quantity in the base units

fn from_base_units(units: f64) -> Self

Create a new quantity from the base units

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