Trait GaloisField

pub trait GaloisField {
    // Required methods
    fn size() -> usize;
    fn valid_codeword(bits: u8) -> bool;
    fn codeword(pow: usize) -> u8;
    fn power(codeword: usize) -> usize;

    // Provided method
    fn codeword_modded(pow: usize) -> u8 { ... }
}

A GF(2^r) Galois field.

Required Methods

fn size() -> usize

Number of unique codewords in the field: 2^r - 1.

fn valid_codeword(bits: u8) -> bool

Check if the given bit pattern is a valid codeword in the field.

fn codeword(pow: usize) -> u8

Map the given power i to codeword αⁱ.

fn power(codeword: usize) -> usize

Map the given codeword aⁱ to its power i.

Provided Methods

fn codeword_modded(pow: usize) -> u8

Map the given power i to codeword α^m ≡ αⁱ (modulo the size of the field.)

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.
