🦀 I wrote a proposal for an #[export] attribute in #rustlang to allow for *dynamic* linking between Rust crates, without losing memory safety at the linker boundary.
This will make other ABI work aimed at Rust FFI directly usable between Rust crates as well.
Tl'dr #rustlang is a great collaboration opportunity for @gnome and @kde.
A long long time ago, #freedesktop initiative was created for precisely this goal. While in many ways it was a success story (especially in terms of establishing standards), it came short in one specific aspect: code collaboration.
Most freedesktop (all?) projects were and are almost exclusively developed and maintained by GNOME folks. That's not very surprising, given that C (being that lowest common denominator) had to be the programming language of choice. Just like most GNOME folks wouldn't want to touch C++, KDE folks don't particularly enjoy coding in C either. I know both have their reasons and the point here is not to play the blame game here.
There is not much point in dwelling in the past here but if we decide to write all future infrastructure/non-UI projects (that would have otherwise been written in C or C++) in Rust, there's a great potential for collaboration, I believe.
Talk is cheap, you could say and I agree. Hence why I've taken some steps in this direction already: github.com/dbus2/

Over the Easter holidays I experimented a bit with building Rust code with meson instead of cargo.
Specifically I tried building a GStreamer plugin with a few dozen Rust dependencies, but the same applies in a similar way to GTK/GNOME applications or literally anything else.

✨ GStreamer Rust bindings 0.20 and Rust plugins 0.10 release is out
This release features the addition of a few convenience APIs, the addition of bindings for some minor APIs and a lot of internal changes to improve performance and code generation.
As part of the optimizations, there are a lot fewer temporary allocations now, e.g. for NUL-terminated strings.
Also, in addition to better performance, the code generation improvements also reduce the binary size considerably.
Some GStreamer plugins saw reductions of 15-20% 🥳

@TauriApps is awesome!
I just made a standalone app for emoji-mart using tauri.
It is very easy to use as a developer, starts fast, binaries are small (2mb for this project) and packaging just works out of the box.
For this project I did not even had to write a single line of rust, so you don't need to be comfortable with #rustlang to be able use it.

The Rust base64 crate got a new release the other day, which removed (or rather deprecated for now) the simple encoding/decoding API and requires quite a bit boilerplate for such a simple task.
The maintainer does not see the point in providing a simpler API for the common cases because if the API is too difficult to use then Rust is just the wrong language for you 🙄
Too bad the crate has such a prominent name on crates.io and is used so widely. I hope that doesn't turn away too many beginners because something as simple as base64 handling is so complicated.
The data-encoding crate looks like a good alternative for the same tasks. It provides the same amount of flexibility while still providing a simple API for the common tasks.
