# core::traits::BitAnd

The bitwise AND operator `&`.

## Signature

```rust theme={null}
pub trait BitAnd
```

## Examples

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

```rust theme={null}
use core::traits::BitAnd;

#[derive(Drop, PartialEq)]
struct Scalar {
    inner: bool,
}

impl BitAndScalar of BitAnd {
    fn bitand(lhs: Scalar, rhs: Scalar) -> Scalar {
       Scalar { inner: lhs.inner & rhs.inner }
    }
}

assert!(Scalar { inner: true } & Scalar { inner: true } == Scalar { inner: true });
assert!(Scalar { inner: true } & Scalar { inner: false } == Scalar { inner: false });
assert!(Scalar { inner: false } & Scalar { inner: true } == Scalar { inner: false });
assert!(Scalar { inner: false } & Scalar { inner: false } == Scalar { inner: false });
```

## Trait functions

### bitand
