Fountain codes

The library implements currently 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

Dependencies

rand

Usage

Add fountaincode as a dependency in Cargo.toml

toml [dependencies] fountaincode = "0.0.1"

Example

```rust let mut buf = Vec::new(); let mut f = File::open("testfile.bin").unwrap(); try!(f.readtoend(&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 under the MTU size let enc = Encoder::new(buf, 1024);

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

for drop in enc { //Encoder is exposed as Iterator, in practice you may want to send over UDP //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.unknownchunks); } Finished(data, stats) => { done = true; println!("finished! {:?}", stats); for i in 0..length { assert!(buforg[i], data[i]); }

    }
}

} ```
