Trait std::ops::ShrAssign ​

右移赋值运算符 >>=。

rust
pub trait ShrAssign<Rhs = Self> {
    // Required method
    fn shr_assign(&mut self, rhs: Rhs);
}

ShrAssign 的实现，用于围绕 usize 的包装。

rust
use std::ops::ShrAssign;

#[derive(Debug, PartialEq)]
struct Scalar(usize);

impl ShrAssign<usize> for Scalar {
    fn shr_assign(&mut self, rhs: usize) {
        self.0 >>= rhs;
    }
}

let mut scalar = Scalar(16);
scalar >>= 2;
assert_eq!(scalar, Scalar(4));

Required Methods ​

shr_assign ​

rust
fn shr_assign(&mut self, rhs: Rhs)

参数：

  • rhs：执行 ^ 操作的右值
rust
let mut x: u8 = 5;
x >>= 1;
assert_eq!(x, 2);

let mut x: u8 = 2;
x >>= 1;
assert_eq!(x, 1);
