Parsing the Redis Serialization Protocol (RESP) in Rust with nom (Part 3)
6In this live coding session, we continue our project focused on parsing the Redis protocol in Rust using the nom library. We tackle various data types within the protocol, including bignumber, bulk error, verbatim string, and more complex structures like maps and sets and pushes.
We also did some refactoring along the way to avoid some unnecessary code duplication and we improved our test suite.
This concludes the basic implementation of parsing the Redis protocol. The library might still require some tweaking but that might be the topic of another video!
