[−][src]Struct ndarray_unit::Unit
Methods
impl Unit
[src]
pub fn new() -> Unit
[src]
Return an Unit with an empty set of BaseUnit
pub fn from_vec(list: Vec<(BaseUnit, i32)>) -> Unit
[src]
Create a Unit from a vector of BaseUnit and their power
Examples
use ndarray_unit::Unit; use ndarray_unit::BaseUnit; let candela_square_divided_by_ampere_cube = Unit::from_vec(vec![(BaseUnit::CANDELA, 2), (BaseUnit::AMPERE, -3)]); println!("{}", candela_square_divided_by_ampere_cube)
Output
// cd²·A⁻³
pub fn get_base_units(&self) -> &HashMap<BaseUnit, i32>
[src]
pub fn get_inverse(&self) -> Unit
[src]
Given an Unit
, return the inverse of this unit.
It inverse the sign of the power of every BaseUnit of the given input Struct
Exemples
use ndarray_unit::Unit; use ndarray_unit::BaseUnit; let unit = Unit::from_vec(vec![(BaseUnit::KELVIN, 2), (BaseUnit::MOLE, -3)]); let inverse = Unit::from_vec(vec![(BaseUnit::KELVIN, -2), (BaseUnit::MOLE, 3)]); assert_eq!(inverse, unit.get_inverse());
pub fn add_single_unit(&mut self, unit: BaseUnit, n: i32)
[src]
Add a BaseUnit (and its power) to an existing mut Unit
Examples
use ndarray_unit::Unit; use ndarray_unit::BaseUnit; let mut meter = Unit::new(); meter.add_single_unit(BaseUnit::METER, 1); let mut meter_per_second = meter.clone(); meter_per_second.add_single_unit(BaseUnit::SECOND, -1); println!("{}", meter_per_second);
Output
// m·s⁻¹

[src]
impl<'_> Div<&'_ Unit> for &'_ Unit
[src]
Given two Unit
s, perform a division between them and return a new Unit
.
It substracts the base_units of the two given Struct
Exemples
use ndarray_unit::Unit; use ndarray_unit::BaseUnit; let meter = Unit::from_vec(vec![(BaseUnit::METER, 1)]); let second_square = Unit::from_vec(vec![(BaseUnit::SECOND, 2)]); let acceleration = &meter / &second_square; // acceleration = Unit { base_units: {METER : 1, SECOND: -2} }
type Output = Unit
The resulting type after applying the /
operator.

impl<'_> Mul<&'_ Unit> for &'_ Unit
[src]
