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.

Any active open source repos built using Rust that need development ?
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 It's technically feature complete, but depends on a unpublished diesel version + has some remaining bugs with certain mysql versions.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

Diesel 2.0.0 RC1
We use libmysqlclient mostly for historic reasons. The mysql crate did just not exist back then when diesel started and rewriting all the internal code now is just something that we did not have the time nor motivation for. That written: Diesel is designed in such a way that connections can be provided by third party crates, even for existing backends. Diesel 2.0 adds explicit documentation for this as part of the connection trait and we are definitively interested to see pure rust implementations for the postges and mysql backend there. Also there is this discussion in the rust-mysql crate repository about a potential diesel integration. If someone is interested in working on this (or the equivalent implementation for postgresql), please reach out to us. We definitively can provide some pointers where to look for stuff and how to generally approach such an implementation. It's likely nothing that's really hard, it just requires someone to spend some work on it.

Reviews of the Diesel ORM, are there better alternatives?
I can understand that this can be frustrating and I know that the situation there is not ideal for diesel. There are certainly things to improve there by either providing a bundling support which builds the native library as part of the normal build process or by implementing a pure rust connection implementation. Both is possible with diesel, but requires some work. At least the pure rust connection implementation is something that can be provided by a third party crate now with upcoming diesel 2.0 release. If you are interested in that checkout this and this issue. As for the bundling support: This requires changes in the mysqlclient-sys and pq-sys crates. Again help there is welcome. In the end it makes me sad that some people have repeating decided that a solution to this problem is to write just another crate instead of helping to fix these issues. This just results in everyone have more work to do, as there are now two non-perfect solutions instead of having one slightly improved solution.
