1.0.0[−][src]Trait core::ops::Div
The division operator /
.
Note that Rhs
is Self
by default, but this is not mandatory.
Examples
Div
idable rational numbers
use std::ops::Div; // By the fundamental theorem of arithmetic, rational numbers in lowest // terms are unique. So, by keeping `Rational`s in reduced form, we can // derive `Eq` and `PartialEq`. #[derive(Debug, Eq, PartialEq)] struct Rational { numerator: usize, denominator: usize, } impl Rational { fn new(numerator: usize, denominator: usize) -> Self { if denominator == 0 { panic!("Zero is an invalid denominator!"); } // Reduce to lowest terms by dividing by the greatest common // divisor. let gcd = gcd(numerator, denominator); Rational { numerator: numerator / gcd, denominator: denominator / gcd, } } } impl Div for Rational { // The division of rational numbers is a closed operation. type Output = Self; fn div(self, rhs: Self) -> Self::Output { if rhs.numerator == 0 { panic!("Cannot divide by zero-valued `Rational`!"); } let numerator = self.numerator * rhs.denominator; let denominator = self.denominator * rhs.numerator; Rational::new(numerator, denominator) } } // Euclid's two-thousand-year-old algorithm for finding the greatest common // divisor. fn gcd(x: usize, y: usize) -> usize { let mut x = x; let mut y = y; while y != 0 { let t = y; y = x % y; x = t; } x } assert_eq!(Rational::new(1, 2), Rational::new(2, 4)); assert_eq!(Rational::new(1, 2) / Rational::new(3, 4), Rational::new(2, 3));Run
Dividing vectors by scalars as in linear algebra
use std::ops::Div; struct Scalar { value: f32 } #[derive(Debug, PartialEq)] struct Vector { value: Vec<f32> } impl Div<Scalar> for Vector { type Output = Self; fn div(self, rhs: Scalar) -> Self::Output { Vector { value: self.value.iter().map(|v| v / rhs.value).collect() } } } let scalar = Scalar { value: 2f32 }; let vector = Vector { value: vec![2f32, 4f32, 6f32] }; assert_eq!(vector / scalar, Vector { value: vec![1f32, 2f32, 3f32] });Run
Associated Types
type Output
The resulting type after applying the /
operator.
