Trait grafix_toolbox::uses::ops::BitOr1.0.0[−][src]

pub trait BitOr<Rhs = Self> {
    type Output;
    fn bitor(self, rhs: Rhs) -> Self::Output;
}
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]);
assert_eq!(bv1 | bv2, expected);

Associated Types

The resulting type after applying the | operator.

Required methods

Performs the | operation.

Examples

assert_eq!(true | false, true);
assert_eq!(false | false, false);
assert_eq!(5u8 | 1u8, 5);
assert_eq!(5u8 | 2u8, 7);

Implementations on Foreign Types

Returns the union of self and rhs as a new HashSet<T, S>.

Examples

use std::collections::HashSet;

let a: HashSet<_> = vec![1, 2, 3].into_iter().collect();
let b: HashSet<_> = vec![3, 4, 5].into_iter().collect();

let set = &a | &b;

let mut i = 0;
let expected = [1, 2, 3, 4, 5];
for x in &set {
    assert!(expected.contains(x));
    i += 1;
}
assert_eq!(i, expected.len());

Returns the union of the two sets of flags.

Returns the union of the two sets of flags.

Returns the union of the two sets of flags.

Returns the union of self and rhs as a new AHashSet<T, S>.

Examples

use ahash::AHashSet;

let a: AHashSet<_> = vec![1, 2, 3].into_iter().collect();
let b: AHashSet<_> = vec![3, 4, 5].into_iter().collect();

let set = &a | &b;

let mut i = 0;
let expected = [1, 2, 3, 4, 5];
for x in &set {
    assert!(expected.contains(x));
    i += 1;
}
assert_eq!(i, expected.len());

Or with 0 ( 0 | 1 = 1)

UTerm | X = X

UInt<Ul, B1> | UInt<Ur, B0> = UInt<Ul | Ur, B1>

X | UTerm = X

UInt<Ul, B1> | UInt<Ur, B1> = UInt<Ul | Ur, B1>

Or with 1 ( 1 | B = 1)

UInt<Ul, B0> | UInt<Ur, B0> = UInt<Ul | Ur, B0>

Or with 0 ( 0 | 0 = 0)

UInt<Ul, B0> | UInt<Ur, B1> = UInt<Ul | Ur, B1>
