This repository contains a Rust implementation of the zstd file format. It aims to provide excellent performance while introducing memory safety.
This codebase has three components:
- the decoder has undergone significant cleanup work and is mostly safe
- the dict builder has been cleaned up, but has some lingering unsafe when calling into the encoder
- the encoder is functional, but still mostly just the raw c2rust translation and hence full of unsafe code
Our decoder is ready for experimental use, but is not yet battle-tested.
The primary way to use this library right now is as a static library that is linked into C projects, e.g.
> cargo build --features=export-symbols -p libzstd-rs-sys --release --lib
> ls target/release/*.a
target/release/liblibzstd_rs_sys.a
In the future we hope to hook into zstd-rs for more convenient usage from rust itself.
We track our performance at https://trifectatechfoundation.github.io/libzstd-rs-sys-bench/.
This project is based on the Zstandard reference implementation.
libzstd-rs-sys is part of Trifecta Tech Foundation's Data compression initiative.
