zstd-rs
Zstandard is a modern successor to zlib, providing better compression faster. Zstd-rs is in developement; it aims to provide excellent performance while introducing memory safety.
The project will provide a dynamic library that is a drop-in replacement for C/C++ counterparts, but has compiled memory-safe Rust code inside. For the high level goals, see our Data compression initiative.
Zstd-rs is part of our Data compression initiative.
