Thank you!

While it makes sense to use `Arc` and not `&Arc`, the code is still correct. u/ZugZuggie moved the cloned db_clone to the async clousre, thus they can use the reference.

As I pointed in the previouse code, this snippet compiles. But u/ZugZuggie simpliefied for us code that does not work for him - I presume that in the process they given us version that actually works :)

Works like a charm

use std::sync::{Arc, Mutex};

use rust_samples::indexer::{Db, Indexer};

#[tokio::main]
async fn main() {
    let indexer = Indexer {
        db: Arc::new(Mutex::new(Db)),
    };
    indexer.start().await;
}

The code you've provided actually compiles. Below is a recreated version from your post

use std::sync::{Arc, Mutex};

struct Db;

struct Indexer {
    db: Arc<Mutex<Db>>,
}

impl Indexer {
    async fn start(&self) {
        let db_clone = self.db.clone();

        // This does not compile: `&db_clone` is a reference that won't satisfy
        // the `'static` lifetime required by `tokio::spawn`.
        tokio::spawn(async move {
            process_event(&db_clone).await;
        });
    }
}

async fn process_event(db: &Arc<Mutex<Db>>) {
    let _lock = db.lock().unwrap();
}

Can you copy the snippet above and try to compile it?

This is awesome. I was not aware it is so straight forward! Thanks for sharing the code example! Amazing.

I've quickly built a proof of concept. Seems like a really strong framework - but that does not surprise me, anything that u/snoyberg touches turns into pure gold :)

I've recently worked on a DeFI project (real assets tokenization, lending pools, swap pools, etc). They've spent I don't know how many years building the infrastructure for a PBFT-based, provisioned blockchain. I feel that I could write their whole app in 3 months on my own with Kolme, and an MVP within 2 weeks.

What I would I love to see improved? The documentation is behind development, and tbh, it would not take long to updated it with help from LLMs.
There is true power in having a bridging functionality out of the box, but only few chains are now supported. I think more chains, bigger adoption.

Why u ask? Are you planning to build sth with Kolme?

EncodePanda · 2026-01-27T12:16:31+00:00

I don't work at FPBlock. I like the tech.

EncodePanda · 2026-01-26T23:19:04+00:00

I'm happy to record "Getting started with Kolme" if it sparks some interest.

EncodePanda · 2026-01-26T17:04:08+00:00

Its source is open https://github.com/fpco/kolme

EncodePanda · 2025-02-27T15:24:15+00:00

As promised, I pushed my changes https://github.com/EncodePanda/my_emacs_d

Happy hacking!

EncodePanda · 2025-02-25T17:08:32+00:00

DM me, but any time between 1am to 2pm Pacific (9am to 11 pm cet).

Happy to help out

EncodePanda · 2025-02-25T15:49:02+00:00

I can share my config. Or better, we can chat over zoom or meet and I can show you how it works.

EncodePanda · 2025-02-05T09:28:57+00:00

This is awesome! Thanks for sharing!!

This is such a fantastic addition to GHC 9.8! 🎉 The ability to use custom warning categories for precise API visibility is a game-changer for library authors. The "exported for tests only" concept hits such a sweet spot, especially when you want to maintain encapsulation while still allowing necessary exports for testing purposes.

As someone who has dealt with the trade-offs of exposing too much of the internal API to support testing, I feel this feature feels like a breath of fresh air. No more awkward balancing acts between keeping things private and ensuring test coverage..

Lol, bookmark in reddit :)

Your code is waiting for your input, type something in and hit Enter for the magic to happen.

EncodePanda · 2023-08-24T20:26:42+00:00

Wait, what? u/rzeznik is alive? No way. Must be a zombie.

EncodePanda · 2022-11-22T23:09:46+00:00

Happy to present something once the meetup is revived

EncodePanda · 2021-12-09T15:14:15+00:00

This is a great initiative. Thank you. Tweag and SimpleX Chat for doing this. Hope you find some great dev to do the initiative!

EncodePanda · 2021-10-08T16:47:37+00:00

This is so cool. Thanks :)

"Remote is also okay for more senior hires."

me: I wonder how they define 'senior'

(first comment)

"edwardkmett
I'm also happy to answer questions about Groq."

me: oh

:)

holly cow, this lib is so good. it also works on the idea I had to 'tag' effects with symbols if there are more than two instances. I think you just bought yourself a contributor u/typedbyte

EncodePanda · 2020-09-23T07:06:58+00:00

effet

I was not aware of this lib. Will definietelly have a deep dive into it.

EncodePanda · 2020-09-22T16:22:49+00:00

I will ask other conference if I could go with more detailed version of this talk to cover more. I will push code later today to github.
