Trait std::ops::MulAssign

pub trait MulAssign<Rhs = Self> {
    fn mul_assign(&mut self, rhs: Rhs);
}

乘法分配运算符 *=。

Examples

use std::ops::MulAssign;

#[derive(Debug, PartialEq)]
struct Frequency { hertz: f64 }

impl MulAssign<f64> for Frequency {
    fn mul_assign(&mut self, rhs: f64) {
        self.hertz *= rhs;
    }
}

let mut frequency = Frequency { hertz: 50.0 };
frequency *= 4.0;
assert_eq!(Frequency { hertz: 200.0 }, frequency);

Required methods

fn mul_assign(&mut self, rhs: Rhs)

执行 *= 操作。

Example

let mut x: u32 = 12;
x *= 2;
assert_eq!(x, 24);
