Struct Field 

pub struct Field;

The field GF(2^8).

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Field

impl Debug for Field

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Field

fn default() -> Field

Returns the “default value” for a type.

impl Eq for Field

impl Field for Field

const ORDER: usize = 256

The order of the field. This is a limit on the number of shards in an encoding.

type Elem = u8

The representational type of the field.

fn add(a: u8, b: u8) -> u8

Add two elements together.

fn mul(a: u8, b: u8) -> u8

Multiply two elements together.

fn div(a: u8, b: u8) -> u8

Divide a by b. Panics is b is zero.

fn exp(elem: u8, n: usize) -> u8

Raise a to the n’th power.

fn zero() -> u8

The “zero” element or additive identity.

fn one() -> u8

The “one” element or multiplicative identity.

fn nth_internal(n: usize) -> u8

fn mul_slice(c: u8, input: &[u8], out: &mut [u8])

Multiply a slice of elements by another. Writes into the output slice.

fn mul_slice_add(c: u8, input: &[u8], out: &mut [u8])

Multiply a slice of elements by another, adding each result to the corresponding value in out.

fn nth_checked(n: usize) -> Option<Self::Elem>

Return Some when n < ORDER, otherwise None.

fn nth(n: usize) -> Self::Elem

Yield the nth element of the field.

impl PartialEq for Field

fn eq(&self, other: &Field) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
