Trait std::ops::Not ​

一元逻辑否定运算符 !。

rust
pub trait Not {
    type Output;

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

用于 Answer 的 Not 的实现，该实现允许使用 ! 反转其值。

rust
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 ​

Output ​

应用 ! 运算符后的结果类型。

rust
type Output

Required Methods ​

not ​

rust
fn not(self) -> Self::Output

返回值：返回否定运算之后的值

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