std::ops

Trait std::ops::Not [−] [src]

pub trait Not {
    type Output;
    fn not(self) -> Self::Output;
}

The Not trait is used to specify the functionality of unary !.

Examples

A trivial implementation of Not. When !Foo happens, it ends up calling not, and therefore, main prints Not-ing!.

use std::ops::Not; #[derive(Copy, Clone)] struct Foo; impl Not for Foo { type Output = Foo; fn not(self) -> Foo { println!("Not-ing!"); self } } fn main() { !Foo; } 
use std::ops::Not;

#[derive(Copy, Clone)]
struct Foo;

impl Not for Foo {
    type Output = Foo;

    fn not(self) -> Foo {
        println!("Not-ing!");
        self
    }
}

fn main() {
    !Foo;
}
