A library crate to parse the content of the Kafka __consumer_offsets internal topic.


  • Most complete parser for __consumer_offsets messages out there
  • Reverse-engineering of Kafka 3.x parsing logic, making it retro-compatible by default
  • Able to parse the subscription and assignment data contained in GroupMetadata messages: beyond what even the Kafka own parser can do
  • Every struct and field is well documented
  • Internal parsing functions are also documented and have references to the code they are based upon: if you read the code, you can go correlate to the Kafka codebase that its imitating
  • Parsing is based on bytes_parser and errors on thiserror, so it's easy to read and handles result errors idiomatically
  • All types exported by this crate are "Thread Safe" and "Async/Await Safe": we enforce the implementation of Sized + Send + Sync + Unpin
  • Support (via feature flags) to parse Unix timestamps via the chrono or time crates
  • Support (via feature flags) for serialization/deserialization via the serde crate
