Trait nom::lib::std::ops::Shr1.0.0[−][src]

pub trait Shr<Rhs = Self> {
    type Output;
    #[must_use]
    pub fn shr(self, rhs: Rhs) -> Self::Output;
}

[−]

The right shift operator >>. Note that because this trait is implemented for all integer types with multiple right-hand-side types, Rust’s type checker has special handling for _ >> _, setting the result type for integer operations to the type of the left-hand-side operand. This means that though a >> b and a.shr(b) are one and the same from an evaluation standpoint, they are different when it comes to type inference.

Examples

An implementation of Shr that lifts the >> operation on integers to a wrapper around usize.

use std::ops::Shr;

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

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

    fn shr(self, Self(rhs): Self) -> Self::Output {
        let Self(lhs) = self;
        Self(lhs >> rhs)
    }
}

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) -> Self::Output {
        // Rotate the vector by `rhs` places.
        let (a, b) = self.vec.split_at(self.vec.len() - rhs);
        let mut spun_vector = vec![];
        spun_vector.extend_from_slice(b);
        spun_vector.extend_from_slice(a);
        Self { vec: spun_vector }
    }
}

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

Associated Types

`type Output`[src][−]

Required methods

`#[must_use] pub fn shr(self, rhs: Rhs) -> Self::Output`[src][−]

Performs the >> operation.

Examples
