s2prot VS Tims-PackageServer

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.

I'm using nom to parse a simple access control ACL in https://github.com/wbbaddons/Tims-PackageServer/blob/master/.... You can see how it looks in the tests of the linked file.

The DSL supports comparison operators, '&&', '||' and nested expressions, while preventing mixing of '&&' and '||' without making precedence clear using parentheses. This DSL should fit 'non-trivial', but it still should be simple enough to easily understand it.
