verasure - Jerasure made simple in V

This is a V implementation of Jerasure2, with a custom wrapper. In V, there is a wrapper to make call pure-v style.

Example

module main

import freeflowuniverse.crystallib.data.verasure

fn main() {
    mut e := verasure.new(16, 4)
    shards := e.encode('Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer consectetur accumsan augue, at pharetra'.bytes())
    println(shards)

    data := e.decode(shards)
    println(data.len)
    println(data.bytestr())
}

1. Create a new Verasure object, with data and parity amount
2. Encode any bytes data
3. Decode shards to get bytes back

Disclamer

This is still in progress, memory management is not yet there. There is still a bug on parity missing.

fn new(segments int, spare int) Verasure

fn test()

struct Shards {
	blocksize int
	data      [][]u8
	parity    [][]u8
}

struct Verasure {
	kntxt &Erasure_t
}

v wrapper

fn (mut v Verasure) encode(data []u8) Shards

fn (mut v Verasure) decode(shards Shards) []u8
