Trait core::ops::BitAnd 1.0.0[−][src]
pub trait BitAnd<Rhs = Self> { type Output; #[must_use] 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);Run
