Overview

Package fec implements Reed Solomon 9/3 forward error correction,

intended to be sent as 9 pieces where 3 uncorrupted parts allows assembly of the message

• func Decode(chunks [][]byte) (data []byte, e error)
• func Encode(data []byte) (chunks [][]byte, e error)

Functions

func Decode

func Decode(chunks [][]byte) (data []byte, e error)

Decode takes a set of shards and if there is sufficient to reassemble, returns the corrected data

func Encode

func Encode(data []byte) (chunks [][]byte, e error)

Encode turns a byte slice into a set of shards with first byte containing the shard number. Previously this code included a CRC32 but this is unnecessary since the shards will be sent wrapped in HMAC protected encryption
