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.

We're building a browser when it's supposed to be impossible
Libraries for a lot of this stuff exist (albeit in many cases not very mature yet):
- https://github.com/pop-os/cosmic-text does text layout (which Taffy explicitly considers out of scope)
- https://github.com/AccessKit/accesskit does accessibility
- https://github.com/servo/rust-cssparser does value-agnostic CSS parsing (it will parse the general syntax but leaves value parsing up to the user, meaning you can easily add support for whatever properties you what). Libraries like https://github.com/parcel-bundler/lightningcss implement parsing for the standard css properties.
- There are crates like https://github.com/BurntSushi/bstr and https://docs.rs/wtf8/latest/wtf8/ for working with non-unicode text
We are planning to add a C API to Taffy, but tbh I feel like C is not very good for this kind of modularised approach. You really want to be able to expose complex APIs with enforced type safety and this isn't possible with C.

Chunking strings in Elixir: how difficult can it be?
As the author of bstr and also the regex implementation that bstr uses to implement word breaking, it is linear time.

A byte string library for Rust
OsStr uses WTF-8 on Windows, and just represents the raw underlying bytes on Unix.
Byte strings can be WTF-8. They can be anything. The problem is that there is no real way to (easily) get the underlying WTF-8 bytes of an OsStr on Windows. So there's no free conversion to and from byte strings.
I wrote more about this in the bstr docs (and don't miss the link to os_str_bytes): https://docs.rs/bstr/latest/bstr/#file-paths-and-os-strings
I'd be happy to answer more questions if you have them. :-) https://github.com/BurntSushi/bstr/discussions

Where is the `str` struct/primitive defined ? I am learning Rust, so don't shoot please :).
Check out bstr, which does this exact thing for its BString and BStr types.

Let's Stop Ascribing Meaning to Code Points (2017)
This is just an FYI. I don't mean to say much to your overall point, although, as someone else who has spent a lot of time doing Unicode-y things, I do tend to agree with you. I had a very similar discussion a bit ago.[1]
Putting that aside, at least with respect to grapheme segmentation, it might be a little simpler than you think. But maybe only a little. The unicode-segmentation crate also does word segmentation, which is quite a bit more complicated than grapheme segmentation. For example, you can write a regex to parse graphemes without too much fuss[2]. (Compare that with the word segmentation regex, much to my chagrin.[3]) Once you build the regex, actually using it is basically as simple as running the regex.[4]
Sadly, not all regex engines will be able to parse that regex due to its use of somewhat obscure Unicode properties. But the Rust regex crate can. :-)
And of course, this somewhat shifts code size to heap size. So there's that too. But bottom line is, if you have a nice regex engine available to you, you can whip up a grapheme segmenter pretty quickly. And some regex engines even have grapheme segmentation built in via \X.

os_str_bytes now has string types!
This is a great idea. I realize the find implementation is not ideal and have considered bringing in an optional dependency to improve performance. I remembered bstr using two-way search, so I was wondering if depending on the full crate for searching would be worthwhile, but I see that changed. Thanks for the tip!

What you don't like about Rust?
Fun little nit-pick that does not detract from your overall point: you can actually count graphemes with a regex and that's exactly what bstr does. :-)

Was Rust Worth It?
Instead of looking at the crates themselves, you might want to check your (or others') Rust application with https://github.com/rust-secure-code/cargo-geiger to get a sense of effective prevalence. I also dispute that the presence of unsafe somewhere in the dependency tree is an issue in itself, but that's a different discussion that many more had in other sub-threads.

There's still plenty. Run cargo geiger on any of your projects and see for yourself.

[Discussion] What crates would you like to see?
You can use cargo-geiger or cargo-crev to check for whether people you trusted (e.g. u/jonhoo ) trust this crate.
-
How do you choose what crate you will use?
The amount of unsafe code is also a factor. cargo geiger is a handy tool for measuring it.

Seems legit
We have cargo-geiger that does just that.

Rosenpass – formally verified post-quantum WireGuard
For that, I believe you need to use cargo-geiger[0] and audit the results.

Hey Rustaceans! Got a question? Ask here (6/2023)!
cargo-geiger is a subcommand you can install which will check all the crates in your dependency graph for unsafe blocks and print out a report (which also shows if a crate has #![forbid(unsafe_code)] or not). You can then inspect those crates' sources to judge their use of unsafe for yourself. I don't think it has a "check" mode that simply errors if your dependency graph contains unsafe though, it's more about just collecting that information.

[CCS Proposal] Preliminary research on rewriting Monero node in Rust
wrt to memory safety, keep in mind that many rust crates use "unsafe" internally. There are tools available that can find these such as cargo-geiger. So I would suggest to avoid unsafe deps as much as possible. Since they cannot be avoided entirely, it is a good idea to keep a list of unsafe deps.
