Over the past couple of months we've been hard at work on libbzip2-rs, a 100% Rust drop-in compatible implementation the bzip2 compression and decompression functionality.

For this project, we used c2rust for the initial translation from the C code to a Rust implementation. The generated Rust code has now been cleaned up and made safe where possible. This post describes our experiences using c2rust for this project.
