Trait std::ops::ShlAssign ​

左移赋值运算符 <<=。

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

ShlAssign 的实现，用于围绕 usize 的包装。

rust
use std::ops::ShlAssign;

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

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

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

Required Methods ​

shl_assign ​

执行 <<= 操作。

rust
fn shl_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, 10);

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