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

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

The `BitAnd` trait is used to specify the functionality of `&`.

# Examples

In this example, the `&` operator is lifted to a trivial `Scalar` type.

    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 {
            Scalar(self.0 & rhs.0)
        }
    }

    fn main() {
        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

In this example, the `BitAnd` trait is implemented for a `BooleanVector` struct.

    use std::ops::BitAnd;

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

    impl BitAnd for BooleanVector {
        type Output = Self;

        fn bitand(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())
        }
    }

    fn main() {
        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);
    }Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
