Expand description
The bitwise OR operator |.
Note that Rhs is Self by default, but this is not mandatory.
Examples
An implementation of BitOr for a wrapper around bool.
use std::ops::BitOr;
#[derive(Debug, PartialEq)]
struct Scalar(bool);
impl BitOr for Scalar {
type Output = Self;
// rhs is the "right-hand side" of the expression `a | b`
fn bitor(self, rhs: Self) -> Self::Output {
Self(self.0 | rhs.0)
}
}
assert_eq!(Scalar(true) | Scalar(true), Scalar(true));
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 BitOr for a wrapper around Vec<bool>.
use std::ops::BitOr;
#[derive(Debug, PartialEq)]
struct BooleanVector(Vec<bool>);
impl BitOr for BooleanVector {
type Output = Self;
fn bitor(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![true, true, true, false]);

sourcepub fn bitor(self, rhs: &HashSet<T, S>) -> HashSet<T, S>
pub fn bitor(self, rhs: &HashSet<T, S>) -> HashSet<T, S>
Returns the union of self and rhs as a new HashSet<T, S>.
