How do you implement API Keys?

by

So I've had this idea for an API for a while but the problem I keep coming back to is authentication. I'm using rocket to actually code it. I looked through the rocket docs and it looks like the closest thing to API key authentication it has are cookies.

Broadcast vs mpsc channels?

by

Hello, I am starting to learn and play around with tokio and multithreaded code. I am now playing around with websockets, I don't quite understand the difference between broadcast and mpsc, and when would you use either, I mean, I am assuming broadcast is intended for multiple clients, but multiple clients were able to connect to my mscp channel, and receive a bit of data (but it was weird and partial). So I don't quite get it.

Inferred types for function calls?

by

Hello, I'm fairly new to Rust and came across this. Can someone explain to me how the following example is able to infer the constant value from the array length passed in? At this point, inferred type generation for function calls are a bit hand wavy, to me, does anyone know of a resource that breaks down all the different ways they can be used (for instance in this example I hadn't seen them used for consts) and what their limitations are in Rust? I often run across a 'this type can not be inferred' error without really knowing why not and just throw in the type to make it go away.

Stack advice

by

Hey all, just looking for some advice. I'd like to do a WASM application, just generally like a calendar + notes app. I'd like it to work on mobile and desktop through the browser. It'll be served through Actix with Diesel for the backend. For the "frontend" I was thinking egui or leptos.

Cutting Down Rust Compile Times From 30 to 2 Minutes With One Thousand Crates

by

Instead of emitting one giant crate containing everything, we tweaked our SQL-to-Rust compiler to split the output into many smaller crates. Each one encapsulating just a portion of the logic, neatly depending on each other, with a single top-level main crate pulling them all in.

Experiences using leptos or yew in production (or giving up trying)?

Introducing Ariel OS - an embedded library OS for small MCUs

by
intro about Ariel OS

We're very happy to announce the first release of Ariel OS, an embedded Rust library OS. Ariel OS runs on small MCUs like nRF5x, RP2xxx, STM32 and ESP32. It is based on Embassy, and turns that into a full-blown RTOS, with preemptive multi-core scheduling and many OS-like conveniences.

Rust is now a government conspiracy

by
A linkedin post by a Senior Embedded Engineer stating: Using Rust is a political solution to deskill a generation of coders to replace higher-cost labor with lower The push for Rust isn't just a technical decision - it's a calculated economic strategy. By forcing rewrites of stable systems in a new language, companies effectively reset the clock on developer experience and expertise. When a C/C++ codebase with 30 years of institutional knowledge gets rewritten in Rust, senior developers with decades of experience suddenly compete on more equal footing with juniors who just graduated. Your 15 years of C++ optimization knowledge? Now worth less than a 22-year-old's six months of Rust bootcamp training. This isn't about memory safety - it's about labor costs. Companies call it "modernization" while quietly erasing the premium they'd otherwise pay for experience. The technical arguments serve as perfect cover for what's really happening: deliberately manufacturing a scenario where they can replace $250K senior engineers with $80K juniors. The pattern is familiar to anyone who's watched other industries. Create artificial obsolescence of existing skills, then exploit the resulting chaos to reset salary expectations and eliminate the leverage that comes with specialized knowledge. This is why language transitions always seem to coincide with hiring freezes and "restructuring." It's never been about technical superiority - it's about breaking labor's bargaining power.

It's getting more and more unhinged on LinkedIn.

Replacing `async_std` by `smol`: What about stdin?

For my library, I want to replace async_std by smol, since the former has been deprecated in favor of the latter. This is mostly just a simple translation (different module structure, names etc.), but what I don't know is how to replace async-std's stdin. Anybody got a hint on that?

Rust questoin, cyclic data structures

by

Question is how to do these in Rust. An example might be a browser DOM: each node has a parent pointer, a list of child pointers, left and right sibling pointers, maybe a CSS node pointer, etc. Inserting or deleting nodes has to repair the pointers to and from the neighboring nodes as needed.

Release: progrs v0.0.1

by

If you belong to the group of people playing World of Warcraft on linux somewhat competitively (there must be dozens of us!), you might be interested in progrs. It is an alternative to warcraftrecorder and used to create videos of your play. It monitors the combat log for interesting events (for now, deaths of players) and creates chapters in the video for easier searching. For now, only "encounters" are supported (might mean just raid bosses, but I've not done any testing in M+), but each try will end up its own video, just as in warcraft recorder.

Typst is "A new markup-based typesetting system that is powerful and easy to learn". It's written in Rust, and particularly attractive because, while providing a CLI interface, it is a proper library that you can easily incorporate into your progress to produce documents. Protip: If you do so, have a look at sys.inputs, it's awesome!

Rust Port of GNU factor (128-bit)

This is just a preliminary release and I plan implementing elliptic curve arithmetic and extending it to 192-bit to cover all the small integers that CADO-NFS doesn't support.

What I learned about Rust while making pastebin

by

Hello, I have recently started to make a pastebin to learn more about Rust and understand the underlying concept of Rust so I first made a very naive pastebin where I used axum to serve the files and used a TCPListener to handle file upload. I didn't use axum to handle file upload because I didn't know how to do it, so basically my program was listening to two different port 8080 and 3000 where on port 3000 I served the files and on 8080 I handle file upload using simple TCP connection. I also used a static variable to name the uploaded file, but in Rust mutable static variable considered unsafe since it could lead to race condition, but at that time I didn't know much about Atomic variables so I wraped the code with unsafe.
