reed-solomon-novelpoly

An implementation of Novel Polynomial Basis and its Application to Reed-Solomon Erasure Codes 1 2 3.

Runs encoding and reconstruction in O(n lg(n)). Note that for small number n there is a static offset due to a walsh transform over the full domain in reconstruction.

Goals

Be really fast for n > 100.

Benchmarking

For benchmarking the implementation against itself and the naive implementation, criterion is used.

cargo bench

Fuzzing

Currently honggfuzz is used.

Install cargo install cargo-hongg and run with:

cargo-hongg fuzz --bin <binary_name>
