Trait Implementations

source

impl Clone for Field

source

fn clone(&self) -> Field

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

source

impl Debug for Field

source

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

Formats the value using the given formatter. Read more

source

impl Default for Field

source

fn default() -> Field

Returns the “default value” for a type. Read more

source

impl Field for Field

source

const ORDER: usize = 256usize

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

type Elem = u8

The representational type of the field.

source

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

Add two elements together.

source

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

Multiply two elements together.

source

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

Divide a by b. Panics is b is zero.

source

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

Raise a to the n’th power.

source

fn zero() -> u8

The “zero” element or additive identity.

source

fn one() -> u8

The “one” element or multiplicative identity.

source

fn nth_internal(n: usize) -> u8

source

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

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

source

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. Read more

source

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. Read more

source

impl PartialEq<Field> for Field

source

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

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

1.0.0 · source

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

This method tests for !=.
