JetBrains has just published the results for their yearly #rustlang developer survey.

There's a lot of interesting data.
A data point some might find surprising: more than a third of Rust developers are using Rust for web development!

An exciting space to be in right now.

The full survey results can be found on jetbrains.com/lp/devecosystem-… including comments from me, Tim and Florian.

A while back I mentioned I was working on #rustlang support for @thunderbird - well, that work is now coming to a head.

Patches in flight for mozilla-central and comm-central that, if merged, will allow us to build Rust-based components in Thunderbird!

En estos días fríos y un poco depresivos me ha dado por aprender #rust #rustlang y me está encantando, no solo por el lenguaje en sí, sino por los maravillosos recursos oficiales de aprendizaje que tienen. Los tres que tienen en su web son muy, muy buenos.

Learn Rust

A language empowering everyone to build reliable and efficient software.

You know how it's hard to learn something you can't see the point of?

I think this is why senior developers, particularly, flock to Rust.
We've been in the trenches, we've been paged at 4am, we've debugged the same missing semicolon or bad indentation errors a thousand times.

You tell me that with just a bit more syntax, Rust can fix my PTSD? I say SIGN ME UP! 🎉

A junior developer, the sweet summer child, only wants things to be easy NOW.

#RustLang isn't optimised for easy NOW.
It's optimised for easy FOREVER.

Did you know that a lot of things in #Rust directly implement the `Ord` trait?

For example `Option<T>` where T: Ord

doc.rust-lang.org/std/option/e…

So you can do:

assert_eq(max(Some(0), Some(1)), Some(1))

assert_eq(max(Some(0), None), Some(0))

assert_eq(min(Some(0), None), None)

There are a lot of other things that implement `Ord`:

QT orhunp_: 🦀 #rustlang quiz

what is the output of this program?

🦀 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.

Watch Philip's talk at #FOSDEM, where he covers the API and prototypes for 'connectbyname', a library function that takes as input a DNS name and returns a TLS connection, as well as a new EDNS(0) option called Proxy Control option that allows stub resolvers to send requirements to a local proxy.

We're developing an #API in #rustlang that can internally use asynchronous #DNS lookups, implement Happy Eyeballs, support #DANE, SVCB/HTTPS, encrypted client hello, etc.

✨ 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.

#GStreamer #Rust #RustLang

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% 🥳
