This is a Rust rewrite of a Go O(n*log n) implementation of Reed-Solomon codes,
ported from the klauspost/reedsolomon,
which is a port of the C++ library catid/leopard.
The original implementation is based on the paper:
S.-J. Lin, T. Y. Al-Naffouri, Y. S. Han, and W.-H. Chung,
"Novel Polynomial Basis with Fast Fourier Transform and Its Application to Reed-Solomon Erasure Codes"
IEEE Trans. on Information Theory, pp. 6284-6299, November, 2016.
The leopard algorithm uses either 8-bit or 16-bit Galois fields with Cantor basis. The 8-bit implementation should be used with up to 256 total shards and 16-bit when more shards are needed.
- Encoding parity shards using 8-bit leopard algorithm
- Reconstructing shards using 8-bit leopard algorithm
- Encoding parity shards using 16-bit leopard algorithm
- Reconstructing shards using 16-bit leopard algorithm
