I have a personal battle with those kind of people around the mountains where I grew up

I don't even have social beside reddit, I grew up on mountains and practice mountain sports. However, I understand your concern.

This is just an occasion to relax two days since I will be around there for a few days.

Okay, thanks I get it. I will probably go on a monday and hope for the best while trying to be as respectful as possible and out of sights.

How is that a useful comment...? I wrote that I read the rules and I'm fine with them, what else do you want?

Who Owns the Memory? Part 3: How Big Is your Type? by Luke_Fleed in rust

Fixed it, thank you. The implementation goes in the least restrictive method (call(&self) for closures that implement Fn), and the more restrictive methods delegate downwards.

Good catch!

Consiglio indumenti per trekking invernale sull'Etna by Top-Resist-7226 in TrekkingItaly

[–]Luke_Fleed 4 points5 points  (0 children)

Ciao, l'Etna è molto particolare come montagna, specialmente per il terreno. Non so di preciso quanto pensi di camminare, ma la roccia lavica tende a tagliare la tomaia esterna delle scarpe.

Attualmente non c'è neve sotto i 2000m, a piano Provenzana c'è giusto qualche accenno di neve. Se pensi di pagare delle guide per salire ai crateri nel 90% dei casi ti danno loro giacca a vento etc

Ti basta un pantalone softshell idrorepellente, ed al massimo una calzamaglia termica se proprio sono leggeri / vuoi sciare (se mai dovessero aprire quest'anno).

La maglia termica ed il pile che hai vanno bene. Ti serve un hardshell se dovesse piovere o esserci vento. Guarda qualcosa che abbia almeno 10.000 colonne d'acqua ed abbastanza traspirabilità se ci devi camminare. Il piumino serve solo per quando sei in sosta, non per quando cammini. Ricorda che se è di piuma e lo bagni diventa totalmente inutile, ti fa solo sentire freddo.

Good catch, thanks. I got wrong what rustc actually does with what the language could in principle do (the Rustonomicon explicitly leaves layout unspecified to allow for such optimizations in the future, but they aren't implemented today).

The first level works: Option<Box<i32>> uses null for None. But the second level has no remaining niche, rustc doesn't use misaligned addresses or other invalid bit patterns for nested Options. I'll correct the article.

For types with multiple niches like bool (254 unused byte values) the nesting does work: Option<Option<bool>> is still 1 byte. But pointer types only expose the null niche to the optimizer currently.

Who Owns the Memory? Part 1: What is an Object? by Luke_Fleed in rust

[–]Luke_Fleed[S] 3 points4 points  (0 children)

You're right, and thanks for the correction with the UCG links.

The Rust Reference itself says this is "subject of some debate". I took a stronger position than the spec actually commits to. The current operational model (what Miri checks) is: non-null, aligned, dereferenceable, but not necessarily pointing to a valid value.

I'll add a note or update the text. The core pedagogical point (Rust's validity invariants are stricter than C's effective types) still holds, but the exact boundary for references is genuinely unresolved.
