}

Trait that encodes common behaviors of unsigned numbers.

Required Associated Constants

const ONE: Self

The number 1 as represented by the current unsigned number.

const BYTES: u8

Number of bytes.

Required Associated Types

type Signed: Signed

The signed representation of this unsigned number.

Required Methods

fn signed(self) -> Self::Signed

Coerce this number bitwise into its signed representation.

fn from_byte(byte: u8) -> Self

Construct from the first byte.

fn as_byte(self) -> u8

Coerce into the lowest 8-bits as a byte.

fn is_smaller_than(self, byte: u8) -> bool

Test if this value is smaller than the specified byte.

fn is_zero(self) -> bool

Test if value is zero.

fn checked_shr(self, value: u32) -> Option<Self>

Perform a shift-right operation.

fn checked_shl(self, value: u32) -> Option<Self>

Perform a shift-left operation.

fn checked_add(self, value: Self) -> Option<Self>

Perform a checked addition.

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.
