pub trait Not {
    type Output;

    // Required method
    fn not(self) -> Self::Output;
}
Expand description

The unary logical negation operator !.

§Examples

An implementation of Not for Answer, which enables the use of ! to invert its value.

use std::ops::Not;

#[derive(Debug, PartialEq)]
enum Answer {
    Yes,
    No,
}

impl Not for Answer {
    type Output = Self;

    fn not(self) -> Self::Output {
        match self {
            Answer::Yes => Answer::No,
            Answer::No => Answer::Yes
        }
    }
}

assert_eq!(!Answer::Yes, Answer::No);
assert_eq!(!Answer::No, Answer::Yes);

Required Associated Types§

source

type Output

The resulting type after applying the ! operator.

Required Methods§

source

fn not(self) -> Self::Output

Performs the unary ! operation.

§Examples
assert_eq!(!true, false);
assert_eq!(!false, true);
assert_eq!(!1u8, 254);
assert_eq!(!0u8, 255);
