[disclaimer: initially posted on Reddit r/rust] [*unrar*](https://docs.rs/unrar) is a library for listing and extracting RAR archives. Hi lemmyrs! Almost 8 years ago, I release my first Rust crate. Today, before I leave *Reddit* at the end of the month due to the recent controversy, after months and years working on and off on this update, as a parting gift, I'm happy to announce the crate's biggest release ever. This really is a milestone release that, among others, allows one to extract files directly into memory -- something people have been asking forever how to do. I've also completely rewritten major parts of the library and am very proud of the way things are looking right now. Utilizing the typestate pattern, the library enforces correct usage at compile time, only exposing methods when they make sense (depending on a combination of [open mode and current cursor position](https://docs.rs/unrar/latest/unrar/#openarchive-cursors)). Before this release, the library was hard to use and it was not possible to skip some files in the archive while, for instance, extracting others. One operation had to be chosen for *all* files. That has changed now. However, the drawback is that iterating archives is now a bit harder since the `Iterator` trait is not implemented for archives that are opened in `Process` mode (since it's hard to enforce an operation at call-site). I have a few ideas how to improve this going forward but input is also always welcome. Anyway, this sets the groundwork architecture and paves the way forward for upcoming releases where ergonomics and other improvements like error types can be the focus. Another major focus of this release was *documentation*: all API items are documented now except for very few exceptions. The crate docs also features a very extensible introduction as well.
