parse-rosetta-rs VS s2prot

Comparing performance of parser libraries

For a very rough comparison of parsers, see https://github.com/rosetta-rs/parse-rosetta-rs

Since this takes a unique approach, would you be interested in adding it to parse-rosetta-rs? Its a repo to help users do a comparative analysis of parser crates, providing some very crude stats to help get them started and allowing them to compare what the APIs look like.

The reason I assume its unrelated to combine is that for the json implementation, a previous version of combine built in about the same time as nom

I'm tempted to collect all of these benchmark repos into a github org to make them easier to find. So far I know of parser, md, argparse, and template languages.

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

vm = virtual machine/memory?

I'm porting this Python library to Rust: https://github.com/Blizzard/s2protocol.

For the shitty, first pass prototype code I've written so far I've seen a ~30-40x speedup compared to the Python implementation and a ~2x speedup compared to a Go implementation by someone else: https://github.com/icza/s2prot.

That is why I chose Rust over a GC language like Go. It's a lot faster out of the box, even without me having a strong understanding of memory operations.
