1.0.0[][src]Trait sp_std::ops::BitAnd

#[lang = "bitand"]pub trait BitAnd<Rhs = Self> {
    type Output;
#[must_use]    pub fn bitand(self, rhs: Rhs) -> Self::Output;
}

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));

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);
