Trait nom::lib::std::ops::Not

pub trait Not {
    type Output;
    #[must_use]
    pub 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);

Associated Types

type Output[−]

The resulting type after applying the ! operator.

Required methods

#[must_use]

pub 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);
