Trait std::ops::Not [src]

pub trait Not<Result> {
    fn not<Result>(&self) -> Result;
}

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

Example

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

struct Foo; impl Not<Foo> for Foo { fn not(&self) -> Foo { println!("Not-ing!"); *self } } fn main() { !Foo; }

struct Foo;

impl Not<Foo> for Foo {
    fn not(&self) -> Foo {
        println!("Not-ing!");
        *self
    }
}

fn main() {
    !Foo;
}
