Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Lezer: A Parsing System for CodeMirror, Inspired by Tree-Sitter
I attempted to use this but was disheartened but the fact that it doesn't statically type node names. Tree Sitter doesn't either but it has much more of an excuse given that it targets C.
https://github.com/lezer-parser/lezer/issues/8
The dev seems mildly hostile to outside involvement too, so I moved on. These days I use Chumsky which is Rust rather than Typescript, but also way more awesome, if you can deal with the often incomprehensible compilation errors at least!

Writing an Equation Solver
We are using technique called parser combinator. And we are using a library chumsky to write parser combinators.

loxcraft: a compiler, language server, and online playground for the Lox programming language
rust-langdev has a lot of libraries for building compilers in Rust. Perhaps you could use these to make your implementation easier, and revisit it later if you want to build things from scratch. I'd suggest logos for lexing, LALRPOP / chumsky for parsing, and rust-gc for garbage collection.

Examples of function-based parsers in chumsky? Examples of unit tests?
The examples that come with chumsky and the chumsky tutorial and guide all define their parsers using closures.

pep-508 v0.2.1 - Zero copy Python dependency parser written with chumsky
chumsky's zero-copy rewrite has reached its first alpha release, and I have migrated my pep-508 parser to it, as suggested in my last announcement.

winnow = toml_edit + combine + nom
On my side, nom is still advancing well and a new major version is in preparation, with some interesting work a new GAT based design inspired from the awesome work on chumsky, that promises to bring great performance with complex error types. 2023 will be fun for parser libraries!

Rust implementation of Python dependency parser for PEP 508
I am using chumsky because I like the API, but it doesn't support zero copy at the moment. Although efficiency is good to have, it is not my primary good. This will probably get supported once chumsky implements support for it (see upstream issue).

Is this a good way to free up some memory?
If you're doing lang dev, maybe check out https://github.com/Kixiron/rust-langdev. I haven't done much since college, not in rust, but I've heard good things

Should I revisit my choice to use nom?
https://github.com/Kixiron/rust-langdev is a pretty nice list of libraries for Rust lang dev including parsers.

Tools for creating a programming language in rust
Someone showed me this repo with a bunch of lang dev libraries a while ago. I haven't done anything with it personally, but it may be of interest to you https://github.com/Kixiron/rust-langdev

Can i use rust to write my compiler??
Absolutely. For a non-exhaustive list of other languages written in Rust, there is https://github.com/alilleybrinker/langs-in-rust. If you are looking for libraries to help you along the way, check out https://github.com/Kixiron/rust-langdev.
