Rust: What the fuck is a borrow checker and why is it yelling at me?

I think this is a pretty bad idea too but, to be fair, languages like Java do a ton of this stuff at compile time too, e.g. Jooq. What I dislike most about macro based DSLs is that inevitably they will end up like C++-style template monstrosities that are poorly documented and where there is no hope of sane autocompletion.

What do you guys recommend for GUI crates?

There's not a lot out there, unfortunately. I briefly tried an experiment to see how far I'd get leveraging webrender for the 2d rendering part, but it was such a moving target that I gave up for the time being.

You can still use a binding to QML perhaps (or even to IMGUI if you don't have too many requirements)

If you're looking for analogues with other languages perhaps it's useful to think of these implementations as extension methods you may have seen in C# or Kotlin. They augment an existing class but they also require both the class and the extension methods to be imported separately.

I also find it odd that after all of the development work that went into the IntelliJ/CLion Rust plugin it still falls over on these use cases. I mean, I'm convinced there's a ton of effort involved to get it to this point, but you'd expect auto-complete to more or less work by now.

I've had similar issues with fairly basic types where it would infer the wrong type (and give me red squigglies), but 'Go to definition' worked flawlessly. I'd expect that to use the same information, but I guess not.

Like you, for me it's still a bit of a blocker to be really productive. Types can become so complex and unwieldy that even looking at the docs can be fairly useless. "Oh, so I know this is a Descriptor<T> but you're not even telling me what T is".

That's one of the most annoying things about the language for me, currently. I understand why the restriction is there but as a regular developer it ends up feeling like such an arbitrary restriction around a very common use case.

You either have a gas leak or there are some snakes on the loose in your apartment.

We use Axum as well and it's pretty nice, can recommend.

Just duplicate the damned code, lol. That's exactly what the compiler does with generics anyway.

Take a look at nom, perhaps?
