Trait std::ops::BitOr 1.0.0[−][src]
Expand description
按位或运算符 |
。
请注意,默认情况下 Rhs
是 Self
,但这不是强制性的。
Examples
BitOr
的实现,用于围绕 bool
的包装。
use std::ops::BitOr; #[derive(Debug, PartialEq)] struct Scalar(bool); impl BitOr for Scalar { type Output = Self; // rhs 是表达式 `a | b` 的 "right-hand side" fn bitor(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(true)); assert_eq!(Scalar(false) | Scalar(true), Scalar(true)); assert_eq!(Scalar(false) | Scalar(false), Scalar(false));Run
BitOr
的实现,用于围绕 Vec<bool>
的包装。
use std::ops::BitOr; #[derive(Debug, PartialEq)] struct BooleanVector(Vec<bool>); impl BitOr for BooleanVector { type Output = Self; fn bitor(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, true, true, false]); assert_eq!(bv1 | bv2, expected);Run

返回 self
和 rhs
的并集作为新的 BTreeSet<T>
。
Examples
use std::collections::BTreeSet; let a: BTreeSet<_> = vec![1, 2, 3].into_iter().collect(); let b: BTreeSet<_> = vec![3, 4, 5].into_iter().collect(); let result = &a | &b; let result_vec: Vec<_> = result.into_iter().collect(); assert_eq!(result_vec, [1, 2, 3, 4, 5]);Run
返回 self
和 rhs
的并集作为新的 HashSet<T, S>
。
Examples
use std::collections::HashSet; let a: HashSet<_> = vec![1, 2, 3].into_iter().collect(); let b: HashSet<_> = vec![3, 4, 5].into_iter().collect(); let set = &a | &b; let mut i = 0; let expected = [1, 2, 3, 4, 5]; for x in &set { assert!(expected.contains(x)); i += 1; } assert_eq!(i, expected.len());Run
