Reed-Solomon BCH

Reed-Solomon BCH encoder and decoder implemented in Rust.

This is a port of python implementation from Wikiversity

This is a fork of https://github.com/mersinvald/reed-solomon-rs - the primary change being that it operates in GF(2^5) instead of GF(2^8).

Setup

toml [dependencies] reed-solomon-32 = "^1.0.0"

Example

```rust use reedsolomon32::Encoder; use reedsolomon32::Decoder;

fn main() { let data = b"Hello World!";

// Length of error correction code
let ecc_len = 8;

// Create encoder and decoder with 
let enc = Encoder::new(ecc_len);
let dec = Decoder::new(ecc_len);

// Encode data
let encoded = enc.encode(&data[..]);

// Simulate some transmission errors
let mut corrupted = *encoded;
for i in 0..4 {
    corrupted[i] = 0x0;
}

// Try to recover data
let known_erasures = [0];
let recovered = dec.correct(&mut corrupted, Some(&known_erasures)).unwrap();

let orig_str = std::str::from_utf8(data).unwrap();
let recv_str = std::str::from_utf8(recovered.data()).unwrap();

println!("message:               {:?}", orig_str);
println!("original data:         {:?}", data);
println!("error correction code: {:?}", encoded.ecc());
println!("corrupted:             {:?}", corrupted);
println!("repaired:              {:?}", recv_str);

} ```
