Trait core::ops::BitXor1.0.0[−][src]

#[lang = "bitxor"]

pub trait BitXor<RHS = Self> {
    type Output;
    fn bitxor(self, rhs: RHS) -> Self::Output;
}

The bitwise XOR operator ^.

Note that RHS is Self by default, but this is not mandatory.

Examples

An implementation of BitXor that lifts ^ to a wrapper around bool.

use std::ops::BitXor;

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

impl BitXor for Scalar {
    type Output = Self;

    // rhs is the "right-hand side" of the expression `a ^ b`
    fn bitxor(self, rhs: Self) -> Self {
        Scalar(self.0 ^ rhs.0)
    }
}

assert_eq!(Scalar(true) ^ Scalar(true), Scalar(false));
assert_eq!(Scalar(true) ^ Scalar(false), Scalar(true));
assert_eq!(Scalar(false) ^ Scalar(true), Scalar(true));
assert_eq!(Scalar(false) ^ Scalar(false), Scalar(false));Run

An implementation of BitXor trait for a wrapper around Vec<bool>.

use std::ops::BitXor;

#[derive(Debug, PartialEq)]
struct BooleanVector(Vec<bool>);

impl BitXor for BooleanVector {
    type Output = Self;

    fn bitxor(self, BooleanVector(rhs): Self) -> Self {
        let BooleanVector(lhs) = self;
        assert_eq!(lhs.len(), rhs.len());
        BooleanVector(lhs.iter()
                         .zip(rhs.iter())
                         .map(|(x, y)| (*x || *y) && !(*x && *y))
                         .collect())
    }
}

let bv1 = BooleanVector(vec![true, true, false, false]);
let bv2 = BooleanVector(vec![true, false, true, false]);
let expected = BooleanVector(vec![false, true, true, false]);
assert_eq!(bv1 ^ bv2, expected);Run

Associated Types
