i've been using relm4 for a while and i'm really happy with it. i love the #elm architecture - your app's state is a struct (or object), your user interface is rendered by a function that takes your state and returns a tree of widgets (or similar), widgets emit messages, messages modify state. i find it so much cleaner and easier to wrap my head around than traditional imperative methods or MVVM.

what are some other nice cross-platform #desktop app frameworks that use this architecture? i'm mainly familiar with #relm4 and #iced in #rust.

#programming #gui #linux

me: what i like about #rust is how easy it makes it to write highly performant code, even when multiple threads are involved

also me whenever i have to think about ownership and lifetimes for more than two seconds: https://turbo.fish/::%3CHashMap%3CString,%20Arc%3CRwLock%3CThingy%3E%3E%3E

thought i found a really weird bug in jiff and spent a good ten or so minutes tracking it down, stepping through functions, etc. eventually i realised i was actually looking at a memory corruption bug in papaya!

do i get a prize for discovering my first memory safety issue in a #rust dependency?

Hmm.

It looks like Microsoft wanted DEV_BROADCAST_HDR to be a discriminated union, but with the different variants having different sizes, presumably so that they could introduce new variants later without breaking existing code.

This is the correct way to accomplish that.

#Rust does something similar for trait object downcasting: check if the desired type is the same as the actual type, and if so, cast the pointer.

Check: https://doc.rust-lang.org/1.85.0/src/core/any.rs.html#225
Cast: https://doc.rust-lang.org/1.85.0/src/core/any.rs.html#294

After Recent Kernel Drama, Rust for Linux Policy Put in Place

The recent Linux kernel drama over Rust code has resulted in the creation of a Rust kernel policy.

New tool from me: I wrote a local aligner that can do approximate reference-based alignment and find genes in a query microbial genome, without a separate indexing step or any temporary disk space usage.

Written fully in Rust and there will be a browser version out later: https://github.com/tmaklin/kbo 1/3

Just released nix-weather, a #rust cli-tool to check how many of your NixOS system’s build dependencies are in a binary cache.

$ nix-weather -n myhost -c /etc/config/

Found Nix Requisites in 8 seconds
Checked 2789 packages in 1 seconds
Found 2676/2789 (95.95%) in cache

This is useful to e.g. “check the weather” before going for an update. If the dependencies you want still haven’t been cached, it can be useful to know you can postpone an update to a later day when the weather is better on the cache.

Feel free to try it out from the GitHub mirror (it’s likely faster than my forgejo instance, and I’d appreciate saving the bandwidth).

NEW BLOGPOST: Why am I writing a #Rust #Rustlang compiler in C?

https://notgull.net/announcing-dozer/

The Cosmic desktop is still alpha but the concept of a desktop enviroment based of Rust is promising. I am looking forward to seeing the progress of this project in the coming months.

rust9x 1.76.0 is close! Now with unwinding, backtrace support and thread parking working :V

i'm working on a little #rust library that lets you define a set of rules and then simulate a cellular automaton. here it is running game of life in a terminal, but you can have arbitrarily many¹ rules and states. i'm planning to make a web app out of this, so you can play around with cellular automata in your browser :3

¹ it's actually just 232, thanks for pointing out that very relevant distinction
