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));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);
