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.

How to call from Rust into JS, Java, C#, Ruby and Python?
I started with JS, and my first step was to write a simple script that checks if a regex is valid. I can call this script from Rust, but there's a problem: Starting a nodejs process takes about 100ms, which is not acceptable, especially for fuzzing.

How do you guard against stack overflows
I noticed this when a test case of a parser I wrote failed in CI on Windows. I then learned that the default stack size on Windows is only 1 MiB whereas its 8 MiB on Linux if I remember correctly. The parser has a hard-coded recursion limit to prevent stack overflows, which is currently set to 128. However, this limit is lower than necessary on Linux, and might still be too high for some platforms (embedded?)

I have to rename Rulex
I was informed that Rulex is a registered trademark and I'm not allowed to use the name for my project. A lawyer contacted me and gave me a week to rename the project, so I have to come up with a different name :(

Melody 0.18 (a sane alternative to regular expressions)
In the other discussion, there's also a link to Rulex, which has similar goals but is more concise. Also claims to compile to multiple regex dialects.

Fuzzing rust-minidump at Mozilla for Embarrassment and Crashes – Part 2
Something similar happened to me a week ago. Someone emailed me that they found panics in rulex, and then created a PR to fix them. They even explained to me how to create a security advisory on GitHub because the panics could be used to DoS someone. It was very helpful.

Where would you put Error enums?
Sorry for not being more specific. Since this is a parser, the span points into the text file that is being parsed, so it's not that relevant for most libraries. Here is the parser, it uses nom parser combinators. Unfortunately, and adding the spans to the errors involves some boilerplate.

Any active open source repos built using Rust that need development ?
I welcome contributions for rulex. It's a medium-sized project that should be fairly easy to understand, and has some "good first issues" :)

Can I use an AGPL licensed crate in my closed source backend?
So I want to use diesel_async in my web backend.

Diesel 2.0.0 RC1
The already linked discussion from last time already contains a lot of information about this. Diesel itself does not provide async operations and that will likely remain that way for a foreseeable future. At least my preferred solution is to keep async support in a separate crate. A prototype for this is currently available here. Keep in mind that this is not released yet, so there might be bugs everywhere. I plan to cut a first release of this crate after the final release of diesel 2.0, which means hopefully soon. As for ETA's: I generally do not give any ETA's for releases, as this is currently a free time project for me.

So, diesel is an ORM that tries to take full advantage of rust's typing expressivity to allow for statically checked, and fast, queries. I absolutely loved it when trying it out the first time.

Reviews of the Diesel ORM, are there better alternatives?
i don't see why you or anyone else would consider it too big of an issue that Diesel doesn't have async. For those who really want async diesel right now, the author already released diesel_async as a stop-gap solution, but even without that there's nothing wrong with using spawn_blocking. It feels worse than it really is to use blocking thread pools; until io_uring is a thing, there's no real getting around the necessity of threads being blocked for I/O and so adding async to the mix doesn't magically make things faster.

What is your go-to database crate for PostgreSQL?
As for now there is an prototype available here. It's technically feature complete, but depends on a unpublished diesel version + has some remaining bugs with certain mysql versions. If that is fixed I will likely publish a first alpha version officially. That can take same time because that's a second large project that needs maintenance time beside diesel itself and that's quite a lot to do in my free time. You can support this work by sponsoring me on github
-
Diesel 2.0.0 RC.0
Async support for diesel currently lives in a separate repository as there are language level blocking issues for publishing a version of this crate where we could commit to a stable release at all. See the corresponding diesel issue for details.

diesel-async: An async version of diesel
Weiznich (the maintainer of Diesel) has created an experimental async version of the diesel Connection and RunQueryDsl traits, which should help with ease-of-use for Diesel within async contexts. It is not yet published on crates, but you can find it here: https://github.com/weiznich/diesel_async
