Struct reed_solomon_erasure::galois_16::Field

pub struct Field;

The field GF(2^16).

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a copy of the value.

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

Performs copy-assignment from source.

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 Field for Field

const ORDER: usize = 65_536usize

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

type Elem = [u8; 2]

The representational type of the field.

fn add(a: [u8; 2], b: [u8; 2]) -> [u8; 2]

Add two elements together.

fn mul(a: [u8; 2], b: [u8; 2]) -> [u8; 2]

Multiply two elements together.

fn div(a: [u8; 2], b: [u8; 2]) -> [u8; 2]

Divide a by b. Panics is b is zero.

fn exp(elem: [u8; 2], n: usize) -> [u8; 2]

Raise a to the n’th power.

fn zero() -> [u8; 2]

The “zero” element or additive identity.

fn one() -> [u8; 2]

The “one” element or multiplicative identity.

fn nth_internal(n: usize) -> [u8; 2]

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

Yield the nth element of the field. Panics if n >= ORDER. Assignment is arbitrary but must be unique to n.

fn mul_slice(elem: Self::Elem, input: &[Self::Elem], out: &mut [Self::Elem])

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

fn mul_slice_add(elem: Self::Elem, input: &[Self::Elem], out: &mut [Self::Elem])

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

impl PartialEq<Field> for Field

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
