Well that was a very interesting #Rustlang pre-RFC text! Effectively arguing that Rust is painting itself into a substructural type system corner, and should recognise this as a fact and take the theoretical framework into focus when applying the paint.

As a logician by training, I'm all for it!

Followed by Jonas Kruckenberg (@jonaskruckenberg.de) taking us into the rabbit hole of how stack unwinding works under the hood, where we cross over from the comfort of rust into asm and elf!! 🦀🐰🐉🔄

something i’ve actually been considering: with „everything is a file“ kinda dead, maybe „everything is just a program“ could be interesting?

every file would basically be its data + a wasm decoder blob that exposes a programmatic handle to the data. wit could make that typesafe too. idk

its both a bit cursed, but at the same time file formats (case in point fonts) have become so complicated that maybe making them just fully turing complete is a simplification actually

I think (?) Raph Levien told me once as a joke that if you wanted to design a font file format today it would just be a self-drawing wasm blob. Kinda the same vibe

🚨there’s a phishing campaign targeting crates.io!

so far no reports of compromise, but if you think you might be (no shame) let the rust security team know!
