Question: Why not use nom crate, or similar parsing library?

[Ben-PH]

If this question comes across as rude, I appologise in advance.

I ask, because I've had good experience parsing stuff with this crate. I'm contributing to a library that parses NixOS flakerefs, which are basically a url with specific constraints. Parsing isn't something I specialise in, but I've had good experience with nom, and it seems to create some really nice and interesting idioms that you don't have access to through standard str inspection.

Like I said, I'm not much of a parsing expert, so I was hoping to hear from people involved in this project. Things like your thoughts on current approach, if you were to consider a parsing library, what considerations would go into making decisions, past experiences, etc.

Look forward to hearing your thoughts.
