Fountain codes

Build status Crates Docs

The library implements the Luby Transform Code in Rust. For more information have a look at Wikipedia or the paper LT codes on IEEE Xplore.

In future I might add RaptorQ or Online code.

Dependencies

rand

Usage

Add fountaincode as a dependency in Cargo.toml

[dependencies]
fountaincode = "*"

Example

let mut buf = Vec::new();
let mut f = File::open("testfile.bin").unwrap();
try!(f.read_to_end(&mut buf));

let length = buf.len();
let buf_org = buf.clone();

//create an Encoder, and set the length of the chunks.
//In case UDP is used you may want to stay below the MTU size
let enc = Encoder::new(buf, 1024);

//create a Decoder
let mut dec = Decoder::new(length, 1024);

//Encoder is exposed as Iterator
//In practice you may want to send over a Binary Error Channel, e.g., UDP
for drop in enc {

    //Decoder catches droplets
    //In practice you may want to listen on a UDP port for packages
    match dec.catch(drop) {
        Missing(stats) => {
            trace!("{:?} chunks are unknown", cnt.unknown_chunks);
        }
        Finished(data, stats) => {
            done = true;
            println!("finished! {:?}", stats);
            for i in 0..length {
                assert!(buf_org[i], data[i]);
            }
            println!("and the data is correct!");
        }
    }
}
