Rust BitXorAssign用法及代碼示例

use std::ops::BitXorAssign;

#[derive(Debug, PartialEq)]
struct Personality {
    has_soul: bool,
    likes_knitting: bool,
}

impl BitXorAssign for Personality {
    fn bitxor_assign(&mut self, rhs: Self) {
        self.has_soul ^= rhs.has_soul;
        self.likes_knitting ^= rhs.likes_knitting;
    }
}

let mut personality = Personality { has_soul: false, likes_knitting: true };
personality ^= Personality { has_soul: true, likes_knitting: true };
assert_eq!(personality, Personality { has_soul: true, likes_knitting: false});
