Fellow Rustaceans,

Sharing a side project: Luna, an in-memory SQL "cache" server for object storage data. Main goals:

- The "Redis" for OLAP, columnar SQL data,
- Easy-to-deploy across different envs, but mostly for cloud setup,
- Distributed/cluster support

Finished porting a memberlist library we heavily use at work from Go to #rustlang. It's my first attempt at writing a non-"hello world" Rust code and I'm loving it.

I'm glad I came across this post about async/await in #rustlang. As one who complained a bit about it, having this context helps me understand it more and appreciate it.

Link doesn’t work.

Any word on when it’s gonna land on stable?

This looks so much better, thanks very much. .is_err() huh.

For compile times, I've read about

- blog.rust-lang.org/2024/05/17/e...

although I don't know if these are already in stable.

Oh, nice. TIL. Thanks.

Been contemplating about what systems language to add to our company's stack for a while. I was considering either #ziglang or #rustlang. Ended up with #rustlang.

You know what.. you're actually right.

TIL that in #rustlang stable, if you use scopeguard's defer, rustfmt doesn't work on any code within the defer scope; only outside.

My feed is mostly politics now; rarely tech. So I don't check it as much anymore, nor do I engage as much. Sadly, the tech landscape is still pretty active over at the birdsite.

In #rustlang, calling async functions from sync code feels as "not quite right" as using unsafe.

Some considerations to think about when integrating LLMs to internal workflows: flowerinthenight.com/blog/2025-02...

Looks like this has now been fixed.

I expected musl-gcc would work the same as zig cc, but it didn't; I had more linker errors pertaining to fstat64, open64, stat64, etc. so I didn't go further. zig cc worked for me at that point.

That was my expectation as well, at least initially. But I got several linker errors pertaining to libunwind, which I think was needed by the 3rd party I was using (libclockbound). I didn't find any inclusion of that library in Zig's musl. The inclusion of the -lunwind fixed that bit.

Building static binaries in CGO using musl and Zig (zig cc).

Carbon is not a programming language (sort of) Within C++, there is a much smaller and cleaner language struggling to get out.

Been following Carbon’s progress for a while now. I appreciate this kind of explanation about its goals, non-goals, and nuances.
