In early 2021 I had a closer look into several aspects of digital signal processing (DSP), including lowpass filters, frequency spectrum analysis, and audio visualization. I used Rust to experiment with this. The Rust ecosystem didn’t offer simple-to-use libraries for my use cases back then, or at least they were Read more…
What I show in this blog post is nothing new or unique, but it is something I wish someone would have shown me in this simplicity in my second or third semester at university. In this post, I briefly explain how you can talk to Linux without the libc or Read more…
The other day I had some fun with assembly and wanted to try to call assembly functions from Rust. Each compiler follows a certain calling convention, that specifies how parameters are passed between functions. The calling convention is part of an ABI, an application binary interface. There are two major Read more…
Update: Since Rust 1.59, the macros global_asm! and asm! are finally stable! I also updated the blog post a little but it is mostly in the state from back then. In this blog post, I show how you can create assembly files next to Rust files and compile everything by Read more…
Update: In the meantime, my knowledge of Rust got better. &str simply uses the layout of a fat pointer. Original article down below. TL;DR: At least on x86_64 a &str is two u64 (16 byte) long. The first u64 is a pointer and the second u64 is the length of Read more…
Even though I’m working with Rust for over 2.5 years now, I unfortunately never made a deep dive into the async/await/future-world. But I started using tokio a few days ago and a few questions came up. Tokio is a runtime for executing futures, great! For this, tokio needs some kind Read more…
