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.

Embeddable Scripting Language for Embedded Rust
A colleague of mine used https://github.com/gluon-lang/gluon with great success in our rust projects. Although it probably can't run in a no_std environment.

loxcraft: a compiler, language server, and online playground for the Lox programming language
Aside from these, if you want some inspiration for a production-grade language built in Rust, you might want to go through the source code of Starlark and Gluon.

Modules and Imports
Some languages, like Zig and Gluon have an import expression, where the imported symbols are under a local constant's name. Gluon then also supports destructuring, and Zig has had multiple proposals for years about it, none of which are canon. That is, code like this:
- Gluon: A New Node.js Framework to Create Desktop Apps
- Rock v0.2.1, a little native toy language I've made with Rust and LLVM.
- Gluon: A static, type inferred and embeddable language written in Rust

Fornjot – The world needs another CAD program
This should be a good use-case for rust-based scripting languages, I think.
I loosely followed a project of that kind a while ago, I don't quite remember if it was Gluon [0] or Dyon [1]. Not sure if these are still active, or if another competitor showed up in meantime.

Or if you wanted something more Rust-native, you could try Gluon.

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).
