1.8.0[−][src]Trait sp_std::ops::ShlAssign
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
pub fn shl_assign(&mut self, rhs: Rhs)
[src]
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);
