fgf — Faster Galois Fields

This is a name reservation. There is no API here yet.

fgf will be the published form of fff, a dependency-free Rust library for binary finite field arithmetic: const-capable scalar elements for GF(2^{8) through GF(2}64) and the canonical Fan–Paar towers, plus safe, runtime-dispatched SIMD kernels over packed byte buffers. It is the arithmetic layer underneath erasure coders, proof systems, and other consumers that operate on packed field elements; it is deliberately not a codec.

The crate is developed in the open and distributed through git today. The rename to fgf and the first real release here happen together at 1.0.0, gated on:

1. AVX-512 kernels validated on hardware that can execute them.
2. A stable, extracted backend detection layer.
3. Closing the remaining vectorization work rather than shipping around it.

Until then:
