♲ @switchingsoftware@mstdn.swiso.org: Hi Fediverse 👋

@LemmyDev is a reddit alternative and currently looking for contributions. They want to join the Fediverse, so there is a lot of work ahead of them 💻

If you are intrigued: With experiences in #rust and/or #activitypub , please offer a helping hand. Without these, feel free to spread the word 🙃

Either way, we are excited for your arrival #Lemmy 🤗

Still my favourite (historical) issue on the #Rust compiler:
"hello world" contains Lovecraft quotes
https://github.com/rust-lang/rust/issues/13871

@tindall I should pick up on #rust.

I'm on chapter 4 of The Rust Book and I have to say that a lot of neurons are coalescing right now on how this stuff works and how things should work. It's like every language I've learned since Pascal had a baby and said "let's treat this kid right".

#rust #rustacean

Making a leaf future for tokio #video #rust https://scitech.video/videos/watch/7f1f0e63-8501-4b38-b52d-d04b70d0b840

New information just in: instead of having been written in #rust, it's written in #clojure. Interesting choice. Publisher says they can't write #rustlang.

Yet.

#Meuse, "a free #Rust private registry, first alpha release," via Reddit:

https://www.reddit.com/r/rust/comments/c5rtm0/meuse_a_free_rust_private_registry_first_alpha/

It looks like a private version control system and crates publishing system that works from "cargo publish". Built in rust, of course.

"std threads vs tokio Runtime" a.k.a. me rambling in VS Code for a few minutes #rust https://scitech.video/videos/watch/a010f45d-0129-4a4e-ac98-7f93964193d6

The other day I happened upon #actixWeb, a high-level web serving framework based on #actix, for #rust.

Oh, dear.

None of the examples and guides work. Absolutely nothing.

Hard pass.

I have to say that Rust having a governance page, profiles of people in charge of different aspects of the project, and a RFC process make me lean heavily toward viewing this as an actual language.

Cmpare this with golang that has... um... something?

#golang #rust

Oh. My.

I just, finally, got my #rustlang #software project to build!

I'm learning the #rust #programming #language by re-implementing parts of my daily work, which I hitherto wrote in #java, mostly.

The most recent addition to my project was #diesel, the de-facto data access engine for rust software.

And I'm applying their Get Started Guide to my work situation.

Oh, dear: there's a lot of magic that goes unspoken in the guide. Minor changes will lead to failed builds.

Note to netizens of the #rustlang hashtag: somehow we have managed to claim #rust for our own on the fediverse and it has slightly more traffic

Cargo's options for overriding dependencies via git or local path are wonderful. It makes it so much more likely that I'll tackle a bugfix for an upstream library when the barrier to building and testing is so low. #rust

Can I just share with you how much of a pain it is to have #rust's #diesel create #sqlite3 database tables for us?

It will tell us when a script fails, and will hint at the WORD near which the error occurred. But not on which LINE.

So if I create multiple tables and an error occurs near KEY: good luck figuring out which!

Learned: do 1 table create instruction at a time. Use diesel's migrations to separate.

Installing #diesel for #rust is a pain, too.

Diesel is a tool to let your #rustlang software speak to a data store. Its usage seems straight-forward. It is used for #crates (rust's method of sharing functionality) at https://crates.io/.
Installing it on a virgin Linux distro like Debian requires undisclosed dependencies.

In Debian's case for sqlite: build-essential, locate, pkg-config, and libsqlite3-dev.

NONE OF THIS IS CLARIFIED IN THE GUIDES - 1/2
