Trait ShlAssign

trait ShlAssign<Rhs = Self>

The left shift assignment operator <<=.

Examples

An implementation of ShlAssign for a wrapper around usize.

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

fn shl_assign(self: &mut Self, rhs: Rhs)

Performs the <<= operation.

Examples

let mut x: u8 = 5;
x <<= 1;
assert_eq!(x, 10);

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