std::ops::Not - Rust
Description: API documentation for the Rust `Not` trait in crate `std`.
Keywords: rust, rustlang, rust-lang, Not

# 1.0.0[−][src]Trait std::ops::Not

    #[lang = "not"]pub trait Not {
        type Output;
    #[must_use]    pub fn not(self) -> Self::Output;
    }

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
