The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Parsing JSON in 500 lines of Rust
And on a related note, this project was for educational purposes, but if the author wants to do more parsing in Rust, there's the excellent `nom` crate [1], which provides a JSON parser as an example [2].
It uses a very similar paradigm to what the author used in the article, and provides a lot of helper utilities. I used it to parse a (very, very small) subset of Markdown recently [3] and enjoyed the experience.

Rust: Packages, Modules, Crates...Oh My!
To see these concepts in action, check out my repository Fun with Nom. It’s a project where I explored the Nom crate during a deep dive early in 2024.

I'm Publishing Matanuska BASIC's ADRs
Part of that inspiration was learning about parser combinators, particularly Rust's nom library. Of course, parser combinators - particularly in Rust - presented a bit of a learning curve. But this incredible post by Bodil Stokke really helped me understand how they worked, and made me feel empowered. In fact, for small DSLs, I often use parser combinators - for instance, with ts-parsec in TypeScript and parsy in Python. If you want to dip your toes in and have a head for functional programming DSLs, this is a great direction to go in.

Challenge accepted: announcing SurrealDB 2.0
Unlike the previous parser, which was based on the nom parser-combinator library, the new parser is an optimised recursive descent parser with a separate lexing step. This change allows for more efficient parsing by separating the tokenisation of the input from the parsing logic itself, streamlining the parsing process.

Planespotting with Rust: using nom to parse ADS-B messages
Just in case you are not familiar with nom, it is a parser combinator written in Rust. The most basic thing you can do with it is import one of its parsing functions, give it some byte or string input and then get a Result as output with the parsed value and the rest of the input or an error if the parser failed. tag for example is used to recognize literal character/byte sequences.

Show HN: Rust nom parsing Starcraft2 Replays into Arrow for Polars data analysis
I may be the only one not familiar, but nom refers to https://github.com/rust-bakery/nom which looks like a pretty handy way to parse binary data in Rust.

Is this a good way to free up some memory?
Lots of people use nom for their parsing needs, but that's not the only game in town and there other options.
What are some alternatives?
When comparing zero and nom you can also consider the following projects:
rust-csv - A CSV parser for Rust, with Serde support.
pest - The Elegant Parser
combine - A parser combinator library for Rust
lalrpop - LR(1) parser generator for Rust
pom - PEG parser combinators using operator overloading without macros.
