core::traits::BitNot

The bitwise NOT operator ~.

Signature

pub trait BitNot

Examples

An implementation of BitNot for a wrapper around u8.

use core::traits::BitNot;

#[derive(Drop, PartialEq)]
struct Wrapper {
    u8: u8,
}

impl BitNotWrapper of BitNot {
    fn bitnot(a: Wrapper) -> Wrapper {
        Wrapper { u8: ~a.u8 }
    }
}

assert!(~Wrapper { u8: 0 } == Wrapper { u8 : 255 });
assert!(~Wrapper { u8: 1 } == Wrapper { u8 : 254 });
