fsst-rs

A pure-Rust, zero-dependency implementation of the FSST string compression algorithm.

FSST is a string compression algorithm meant for use in database systems. It was designed by Peter Boncz, Thomas Neumann, and Viktor Leis. It provides 1-3GB/sec compression and decompression of strings at compression rates competitive with or better than LZ4.

This implementation is somewhat inspired by the MIT-licensed implementation from the paper authors, written in C++, but it is mostly written from a careful reading of the paper.

NOTE: This current implementation is still in-progress and is not production ready, please use at your own risk.

NOTE: This crate only works on little-endian architectures currently. There are no current plans to support big-endian targets.
