Trait scale_info::prelude::ops::Not

pub trait Not {
    type Output;

    // Required method
    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);

Required Associated Types

type Output

The resulting type after applying the ! operator.

Required Methods

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);

impl<'a, T, O> Not for &'a mut BitSlice<T, O>where T: BitStore, O: BitOrder,

Inverts each bit in the bit-slice.

Unlike the &, |, and ^ operators, this implementation is guaranteed to update each memory element only once, and is not required to traverse every live bit in the underlying region.

type Output = &'a mut BitSlice<T, O>

impl<A, O> Not for BitArray<A, O>where A: BitViewSized, O: BitOrder,

type Output = BitArray<A, O>

type Output = BitBox<T, O>

impl<T, O> Not for BitVec<T, O>where T: BitStore, O: BitOrder,

This implementation inverts all elements in the live buffer. You cannot rely on the value of bits in the buffer that are outside the domain of BitVec::as_mut_bitslice.

type Output = BitVec<T, O>
