I'm looking for a remote Rust/Elixir role (EU-friendly timezones, US East is ok).
I have 7 years of #rustlang, 9 years of #elixirlang, 20+ years of #linux.
I have over 20 years of experience as a professional developer, and I've been working remotely for 12 years, during which I helped US and EU companies build reliable software.
On the side, I've been developing #asciinema, the best tool to record and stream your terminal sessions. I talk about it in the context of Rust in this #RustaceanStation interview: rustacean-station.org/episode/…
My current contract ends soon, so this is a great time to talk! I'm open to both full-time roles and short term contracts.

Boost please!

RE: hachyderm.io/@conjured_ink/115…
I’m gonna boost this again cause we really haven’t gotten very many applications but we could really really use the engineering help, esp if you’re an experienced #Rust #RustLang engineer.
Open source drive bys are great but having a set of folks who are willing and able to commit to just 5 hours a week would make a world of difference for the project. Please take a look and lmk if you have any questions!

🦀 It's not ready for an official announcement yet, but we're working on a small DB-backed worker queue in Rust.
It's a recurring ask from clients, and I couldn't find anything "production ready" out there.
It's built on top of crates.io's queue. We moved to sqlx (from diesel) as well.
Can we get some eyeballs on it? Feel free to comment here and/or create an issue. A retoot and a ⭐ would also help, of course... 😉

Async from scratch 1: What's in a Future, anyway? | natkr's ramblings
There are a lot of guides about how to use async Rust from a "user's perspective", but I think it's also worth understanding how it works, what those async blocks actually mean. Why you get all those weird pinning errors.natkr.com
🦀 I've improved the implementation behind all the string formatting macros in Rust: println!(), panic!(), format!(), write!(), log::info!(), and so on. (That is, everything based on format_args!().) They will compile a bit faster, use a bit less memory while compiling, result in smaller binaries, and produce more efficient code! 🎉
'Hello world' compiles 3% faster and a few bigger projects like Ripgrep and Cargo compile 1.5% to 2% faster. And those binaries are roughly 2% smaller. 🎊
This change will be available in Rust Nightly tomorrow, and should ship as part of Rust 1.93.0 in January.
@veeso_dev explores the async trap in Rust, how it hurts library APIs, and how tools like maybe-fut can help.

I'd like to parse ipv4 addresses given as command line argument values.
I have got two arguments accepting ipv4 address.
If I specify single such option all is fine.
If I specify both, I 'm getting error like this:

I'm excited to share what I've been working on with @erikjee: RustNL's #rustlang Maintainers Fund!
Many people and companies contribute to Rust, but there are fewer and fewer paid positions for general maintenance (reviews,cleanups,etc). We need to fix that.
General maintenance is one of the most fundamental jobs in an open source project, but is one of the hardest to get paid for. Adding new features gets you promoted; keeping the lights on does not.
But everything depends on it. Code needs reviews, cleanups, docs. New contributors need mentors, etc.
A significant number of Rust maintainers who got paid for that have lost or quit their job recently. Due to RTO policies, a shift in responsibilities, budget cuts, and/or burnout. This is already quite noticable in the Rust project: longer review queues and more technical debt. This is a problem.
Through RustNL, the non-profit foundation behind the largest Rust conference (RustWeek) and the Rust Project's All Hands, we are setting up a fund to provide stable jobs for Rust maintainers. We want to employ six full-time maintainers in 2026.
Additionally, we'll provide internships and mentorship, to help retain promising new contributors. Not only do we need to make sure the current generation of maintainers doesn't burn out, we need to work on the next generation of maintainers too.
What we need now is companies who rely on Rust to step up and contribute financially. Having your business rely on the work of unpaid volunteers is not sustainable in the long term. It's a risk.
And if your company contributes to Rust, keeping the project well-maintained will accelerate your work.
Over the last few months, we have spoken to the Rust Foundation and several big companies about our plans. The input we've received and the positive reactions so far makes us believe we can make this happen. Today, we are publishing our plans for a wider audience, in search for the required funding.
If your company is interested in funding Rust maintainers, please reach out to me or @erikjee!
You can find our sponsors prospectus here: rustnl.org/resources/Rust-Main…
Let me know if you want to talk! 💛

new #rustlang crate drop: iddqd! ID-based maps where keys are borrowed from values. Four maps are included: IdOrdMap, IdHashMap, a bijective (1:1) BiHashMap and a trijective (1:1:1) TriHashMap.
At Oxide we've found this pattern to be extraordinarily useful. iddqd is no-std compatible, too!
![use iddqd::{IdOrdMap, IdOrdItem, id_upcast};
#[derive(Debug)]
struct User {
name: String,
age: u8,
}
// Implement IdOrdItem so the map knows how to get the key from the value.
impl IdOrdItem for User {
// The key type can borrow from the value.
type Key<'a> = &'a str;
fn key(&self) -> Self::Key<'_> {
&self.name
}
id_upcast!();
}
let mut users = IdOrdMap::<User>::new();
// You must pick an insertion behavior. insert_unique returns an error if
// the key already exists.
users.insert_unique(User { name: "Alice".to_string(), age: 30 }).unwrap();
users.insert_unique(User { name: "Bob".to_string(), age: 35 }).unwrap();
// Lookup by name:
assert_eq!(users.get("Alice").unwrap().age, 30);
assert_eq!(users.get("Bob").unwrap().age, 35);
// Iterate over users:
for user in &users {
println!("User {}: {}", user.name, user.age);
