    fn bitor_assign(&mut self, rhs: Rhs);
}
Expand description

按位或赋值运算符 |=。

Examples

use std::ops::BitOrAssign;

#[derive(Debug, PartialEq)]
struct PersonalPreferences {
    likes_cats: bool,
    likes_dogs: bool,
}

impl BitOrAssign for PersonalPreferences {
    fn bitor_assign(&mut self, rhs: Self) {
        self.likes_cats |= rhs.likes_cats;
        self.likes_dogs |= rhs.likes_dogs;
    }
}

let mut prefs = PersonalPreferences { likes_cats: true, likes_dogs: false };
prefs |= PersonalPreferences { likes_cats: false, likes_dogs: true };
assert_eq!(prefs, PersonalPreferences { likes_cats: true, likes_dogs: true });

Required methods

执行 |= 操作。

Examples

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

let mut x = false;
x |= false;
assert_eq!(x, false);

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

let mut x: u8 = 5;
x |= 2;
assert_eq!(x, 7);
