Is there a general name to the way the data is compressed/serialized in SC2 Replays? Yesterday somebody was talking about other ways to serialize/pack data with borsh but not sure it's at all similar... Is the SC1 broodwar replay format similar with byte-alignment and bit "packing"? BTW I call the parsers "bitpacked" or "byte-aligned", but I'm not sure what the right name for them is...

SC2 replays are MPQ files, which is a proprietary format created and used by Blizzard. It's an archive that may contain multiple files stored with different compression and optionally encrypted. I wrote a lib to parse MPQ files that embodies SC2Replays: https://github.com/icza/mpq. I also wrote an SC2 replay parser that is more or less a port of the official s2protocol: https://github.com/icza/s2prot

I mean for example https://github.com/sebosp/s2protocol-rs/blob/755098fb86ab6b1... I hacked my way around the json protocol specification, an enum has n types, using log I can find the number of bits I need to read to uniquely identify each variant, that kind of serialization I wonder the name of.

I'm not sure about an official name, I also just call it "bitpacked".

Thank you for your work on s2prot I spent a lot of time with it and file watchers to gather stats about my matches while I sat in queues
