Thanks for the info! I guess it also makes sense as I realized after posting, if it did use the result of malloc unused it should crash immediately due to references into the zero page segment, thus can't have been what I saw.

Do you happen to use memory resource limits? I used to run Firefox under some, like everything, to prevent it from potentially making the whole system unresponsible, and at the same time had frequent cases of Firefox showing random visual c

If the code in the closure moves a value, then the closure becomes an FnOnce and does move the value out of the context. That's what you probably have in mind. So, Rust does support partially-moving closures, and does so automatically.

No, unless you ask for it via the `move` keyword in front of the closure. This works fine: https://play.rust-lang.org/?version=stable&mode=debug&editio...

There's an independent reimplementation of the PIO assembler here: https://crates.io/crates/pio -- I haven't tried it so don't know how good.

I think the hard drive platter moves in the wrong direction--it pushes the head into the platter instead of away from it if it gets too close.

I wonder if they sensed that at some point number plates would be automatically recorded wherever you drive, even when not causing an accident or doing anything illegal. Just a funny coincidence or is there some connection?: OP writes that

I would expect that this increases the gap between new and old phones / makes old phones unusable more quickly: new phones will typically have enough RAM and can live with the 9% less efficient memory use, and will see the 5-10% speedu

That sounds plausible. I've sent them a mail.

OK, but they wrote "At the end of the last century", which implies towards 2000 not 1900.

If we're talking about constructing structs, like in `Foo { bar, baz: 123 }` (with the `bar` style shortcut in it), I have used that kind of syntax 10 times in 16 KLOC of Rust. Not a lot, but it does happen, and I found it kinda neat w

I was looking at the main branch, and described the situation there. They have a different branch for the optimization work; in that branch, they do mark those functions as `unsafe` (and already did when I posted).

Using clone or Arc with boxing everywhere to avoid using references with lifetimes at all will lead to code that's slower than Go/Java, yes, unless you're just cloning small objects that don't internally use heap alloc

Yes, but their code appears to actually be `unsafe` (in the Rust terminology sense) without specifying that in their function declarations. They use `unsafe` inside their `slice` function, but return a value that is unsafe to use, hence `sl

Interesting, this Gil Trythall piece is the tune in the Commodore C-64 game "Thing on a Spring", isn't it. I didn't know that was a pre-existing piece. https://www.youtube.com/watch?v=AeRP8rQ-07I https:

I've been using genawaiter[1] for writing generators in Rust. Are there things you can't build on top of async-await? Or is it just that it's simpler without that indirection? [1]: https://crates.io/crates&#x2
