    pub trait BitAndAssign<Rhs = Self> {
        // Required method
        fn bitand_assign(&mut self, rhs: Rhs);
    }

Expand description

The bitwise AND assignment operator `&=`.

## Examples

An implementation of `BitAndAssign` that lifts the `&=` operator to a wrapper around `bool`.

    use std::ops::BitAndAssign;

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

    impl BitAndAssign for Scalar {
        // rhs is the "right-hand side" of the expression `a &= b`
        fn bitand_assign(&mut self, rhs: Self) {
            *self = Self(self.0 & rhs.0)
        }
    }

    let mut scalar = Scalar(true);
    scalar &= Scalar(true);
    assert_eq!(scalar, Scalar(true));

    let mut scalar = Scalar(true);
    scalar &= Scalar(false);
    assert_eq!(scalar, Scalar(false));

    let mut scalar = Scalar(false);
    scalar &= Scalar(true);
    assert_eq!(scalar, Scalar(false));

    let mut scalar = Scalar(false);
    scalar &= Scalar(false);
    assert_eq!(scalar, Scalar(false));

Run

Here, the `BitAndAssign` trait is implemented for a wrapper around `Vec<bool>`.

    use std::ops::BitAndAssign;

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

    impl BitAndAssign for BooleanVector {
        // `rhs` is the "right-hand side" of the expression `a &= b`.
        fn bitand_assign(&mut self, rhs: Self) {
            assert_eq!(self.0.len(), rhs.0.len());
            *self = Self(
                self.0
                    .iter()
                    .zip(rhs.0.iter())
                    .map(|(x, y)| *x & *y)
                    .collect()
            );
        }
    }

    let mut bv = BooleanVector(vec![true, true, false, false]);
    bv &= BooleanVector(vec![true, false, true, false]);
    let expected = BooleanVector(vec![true, false, false, false]);
    assert_eq!(bv, expected);

## Required Methods§

source

#### fn bitand_assign(&mut self, rhs: Rhs)

Performs the `&=` operation.

##### Examples

    let mut x = true;
    x &= false;
    assert_eq!(x, false);

    let mut x = true;
    x &= true;
    assert_eq!(x, true);

    let mut x: u8 = 5;
    x &= 1;
    assert_eq!(x, 1);

    let mut x: u8 = 5;
    x &= 2;
    assert_eq!(x, 0);
