Kumamoto-san started feed-rs a while ago, but moved on to other things.
He was kind enough to add me as a maintainer last year, but unfortunately I haven't had much time to learn Rust and keep working on feed-rs in the interim.
I finally got around to publishing 0.2.0.
Its my first "real" Rust project - I wanted something a little more than the exercism examples to learn some Rust, so its probably full of mistakes and poor code but clippy seems happy. 
Key changes:
- 2018 edition
- Align feed model around Atom spec
- Switch to event-based parser (xml-rs) to reduce peak memory usage and use of clone()
- Expanded test coverage
- Documentation improvements
I do plan on using this in a different project (a replacement for fever, a web+app based RSS/Atom reader that is no longer maintained), so I'm expecting to issue a few more releases to feed-rs to address bugs, handle more of the RSS spec etc.
Happy to take feedback, bug reports, broken RSS/Atom feeds etc at the GitHub repo.
Thanks!
