# Trait core::ops::BitAnd
1.0.0[−][src]

    pub trait BitAnd<Rhs = Self> {
        type Output;
        fn bitand(self, rhs: Rhs) -> Self::Output;
    }

Expand description

The bitwise AND operator `&`.

Note that `Rhs` is `Self` by default, but this is not mandatory.

# Examples

An implementation of `BitAnd` for a wrapper around `bool`.

    use std::ops::BitAnd;

    #[derive(Debug, PartialEq)]
    struct Scalar(bool);

    impl BitAnd for Scalar {
        type Output = Self;

        // rhs is the "right-hand side" of the expression `a & b`
        fn bitand(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(false));
    assert_eq!(Scalar(false) & Scalar(true), Scalar(false));
    assert_eq!(Scalar(false) & Scalar(false), Scalar(false));

Run

An implementation of `BitAnd` for a wrapper around `Vec<bool>`.

    use std::ops::BitAnd;

    #[derive(Debug, PartialEq)]
    struct BooleanVector(Vec<bool>);

    impl BitAnd for BooleanVector {
        type Output = Self;

        fn bitand(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, false, false, false]);
    assert_eq!(bv1 & bv2, expected);

## Associated Types

[src]
`type Output`

The resulting type after applying the `&` operator.

## Required methods

[src]
`fn bitand(self, rhs: Rhs) -> Self::Output`

Performs the `&` operation.

# Examples

    assert_eq!(true & false, false);
    assert_eq!(true & true, true);
    assert_eq!(5u8 & 1u8, 1);
    assert_eq!(5u8 & 2u8, 0);
