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.

bitcode 0.4 release - binary serialization format
I was also under the false impression that bitwise encoding was slow. When I first implemented bitcode with bitvec I got performance 20x worse than bincode. After writing my own implementation I was able to get much better performance.

An optimized replacement of the infamous std::vector<🅱️ool>
interesting; i'll have to compare this to my rust counterpart. your numbers indicate some clever implementations i'd love to read

You need to stop idolizing programming languages.
Not to mention having a lackluster std which causes you to use nonstardard not so well documented crates and a 40K LoC library to do "bit-twiddling" (the lib, https://github.com/bitvecto-rs/bitvec the blog that says "twiddle bits" https://blog.adamchalmers.com/making-a-dns-client/ and for crying out loud the blogger also used the language the author mentioned and I quote "ergonomics AND speed AND correctness")
- bit-twiddling tricks. It's the perfect example of Rust's no-compromises "ergonomics AND speed AND correctness" ideals

An Armful of CHERIs: Memory Safety in the processor. Do we still need safe languages with CHERI?
https://github.com/bitvecto-rs/bitvec/issues/135 is a very funny read about how to perform inttoptr with provenance retention
-
bitvec 1.0.0 Released
Technically #135 gives me license to yank affected crates, but since the only exploit is "Miri crashes exactly one test out of the suite" it's not really worth it to be a stickler. Call it a truce
-
What are some creative/advanced uses of macro_rules?
My friend Nika wrote a macro that packs a sequence of 1, 0, … tokens into a correctly structured bit-buffer, adaptable over any register type or bit-ordering, at compile time. It's now basically this whole file
-
Where do I document a published crate?
if you are interested in a user manual, you can use mdbook as well. for an example, my bitvec project uses mdbook (book.toml) and a github action (.github/workflows/gh-pages.yml) to compile the guide and host it as a github pages website. it's slightly more complicated, and i'd like docs.rs to follow hexdoc.pm's example of hosting both api docs and prose, but until then this is a pretty reasonable solution.

When and how to use traits?
i would browse the standard library, tower, nom, or my own bitvec to see layout and trait/record separation. in particular, std::io and std::net may be of use: io::Read and io::Write are pervasive examples of implementing unixy file-descriptor-like behavior in the type system

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 is the state of the art for creating domain-specific languages (DSLs) with Rust?
As much as I love nom as well as other parser combinator libraries, regex-based parsers, BNF/EBNF-based parsers, etc. I always end up going back to plain old text-based char-by-char scanners.
-
What's everyone working on this week (22/2023)?
I am using nom / nom_locate to build the parser side because I've done a handful of other projects with it, and I plan to use tower-lsp to hook up the language server side.
-
Tokenizing
Look into a parsing library such as https://github.com/rust-bakery/nom
-
Something like pydantic but for just strings?
If we were in /r/learnrust I'd have recommended the nom crate for this.

lua bytecode parser written in rust
Thanks to the flexibility of [nom](https://github.com/rust-bakery/nom), it is very easy to write your own parser in rust, read [this article](https://github.com/metaworm/luac-parser-rs/wiki/Write-custom-luac-parser) to learn how to write a luac parser
-
Should I revisit my choice to use nom?
I've been working on an assembler and right now it uses nom. While nom isn't great for error messages, good error messages will be important for this particular assembler (current code), so I've been attempting to use the methods described by Eyal Kalderon in Error recovery with parser combinators (using nom).
What are some alternatives?
