# 1.0.0[−][src]Trait core::ops::Not

    #[lang = "not"]
    pub trait Not {
        type Output;
        #[must_use]
    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 = Answer;

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

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

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
