Trait std::ops::Shr

pub trait Shr<RHS> {
    type Output;
    fn shr(self, rhs: RHS) -> Self::Output;
}

The Shr trait is used to specify the functionality of >>.

Examples

An implementation of Shr that lifts the >> operation on integers to a Scalar struct.

use std::ops::Shr;

#[derive(PartialEq, Debug)]
struct Scalar(usize);

impl Shr<Scalar> for Scalar {
    type Output = Self;

    fn shr(self, Scalar(rhs): Self) -> Scalar {
        let Scalar(lhs) = self;
        Scalar(lhs >> rhs)
    }
}
fn main() {
    assert_eq!(Scalar(16) >> Scalar(2), Scalar(4));
}

An implementation of Shr that spins a vector rightward by a given amount.

use std::ops::Shr;

#[derive(PartialEq, Debug)]
struct SpinVector<T: Clone> {
    vec: Vec<T>,
}

impl<T: Clone> Shr<usize> for SpinVector<T> {
    type Output = Self;

    fn shr(self, rhs: usize) -> SpinVector<T> {
        // rotate the vector by `rhs` places
        let (a, b) = self.vec.split_at(self.vec.len() - rhs);
        let mut spun_vector: Vec<T> = vec![];
        spun_vector.extend_from_slice(b);
        spun_vector.extend_from_slice(a);
        SpinVector { vec: spun_vector }
    }
}

fn main() {
    assert_eq!(SpinVector { vec: vec![0, 1, 2, 3, 4] } >> 2,
               SpinVector { vec: vec![3, 4, 0, 1, 2] });
}
