Trait std::ops::BitOr

#[lang = "bitor"]
pub trait BitOr<RHS = Self> {
    type Output;
    fn bitor(self, rhs: RHS) -> Self::Output;
}

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 {
        Scalar(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, 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).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]);
assert_eq!(bv1 | bv2, expected);

Associated Types

The resulting type after applying the | operator.

Required Methods

Performs the | operation.
