Trait std::ops::BitXor

1.0.0· source · [−]
pub trait BitXor<Rhs = Self> {
    type Output;
    fn bitxor(self, rhs: Rhs) -> Self::Output;
}
Expand description

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::Output {
        Self(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, Self(rhs): Self) -> Self::Output {
        let Self(lhs) = self;
        assert_eq!(lhs.len(), rhs.len());
        Self(
            lhs.iter()
                .zip(rhs.iter())
                .map(|(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);
