bzip2-rs
Bzip2 is a file compression program that is widely deployed and supported e.g. as part of zip.
bzip2-rs is available as a drop-in compatible C library and via the bzip2 crate. The implementation was created using c2rust, and it is now faster than the C original.
bzip2-rs is part of our Data compression initiative.
About
The development of bzip2, started Oct 2024. We used c2rust to translate the original bzip2 C code to Rust.
In June of 2025 we released version 0.6.0 of the bzip2 crate, that uses our 100% Rust implementation, see the blog post bzip2 crate switches from C to 100% rust.
Releases are available on GitHub, and also through the bzip2 crate we now maintain.
Roadmap
No feature development is currently planned. See the workplan.

bzip2 crate switches from C to 100% rust
Today we published bzip2 version 0.6.0, which uses our rust implementation of the bzip2 algorithm, libbz2-rs-sys, by default. The bzip2 crate is now faster and easier to cross-compile.
