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".
