Trait BaseOps 

pub trait BaseOps: Copy {
    type U;

    const NUMBITS: u8;
    const MINVAL: Self;
    const MAXVAL: Self;

    // Required methods
    fn from_u8(v: u8) -> Self;
    fn from_unsigned(v: Wrapping<Self::U>) -> Self;
    fn to_unsigned(&self) -> Wrapping<Self::U>;
    fn fls(&self) -> u8;
}

Internal trait for basic operations on the output type.

Required Associated Constants

const NUMBITS: u8

Number of bits in type Self.

const MINVAL: Self

Smallest possible value of type Self.

const MAXVAL: Self

Biggest possible value of type Self.

Required Associated Types

type U

Unsigned companion of Self.

Required Methods

fn from_u8(v: u8) -> Self

Convert an u8 to Self.

fn from_unsigned(v: Wrapping<Self::U>) -> Self

Convert a wrapping unsigned to a bit identical Self.

fn to_unsigned(&self) -> Wrapping<Self::U>

Convert self to a bit identical wrapping unsigned.

fn fls(&self) -> u8

Find last bit set in self.

Bit 0 -> returns 1; Bit 1 -> returns 2; …

If no bit set -> returns 0.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
