So it's more like a "Look, it's possible to do this in Rust!"

than

"We did it in Rust, and we believe it's better because ..."

?



sort by: page size:

I don’t think that’s completely correct - I think “written in rust” being bandied about as a feature is a somewhat unique feature of the Rust community

Because it's not written in Rust!

(1) does not seem true, they have documented some seemingly detailed reasons why Rust is not always the right choice, and acknowledge that in many cases it is: https://github.com/carbon-language/carbon-lang/blob/trunk/do...

"It's written in Rust."

The rewrite in Rust comment just had to appear somewhere in that reply thread .

Coming from a Rust enjoyer. Don't use it myself but see the benefits. But those oneliners always make me chuckle.


It says in the description:

>Written in Rust, btw xD


I appreciate that. It ends up being a small diff but does help clarify, I think. Thank you! https://github.com/rust-lang/blog.rust-lang.org/pull/674

"Rust code is wonderful to write and read"

Writing I'm not sure, reading it's just awful, everytime someone show his project on HN I check github and I'm baffled how the code looks bad as a human reader. (){}<>''-_


It's the perfect occasion to rewrite it in rust.

There, I've said it


So if i loop back to the original message "Written in Rust", what they mean to convey is that "this is done by smart people" ;)

My favourite part:

> our verification work resulted in uncovering and fixing a bug in Rust’s standard library, demonstrating that our model of Rust is realistic enough to be useful.

The bug was https://github.com/rust-lang/rust/issues/41622.


Because it is Rust code?!?

"...An easy tutorial in Rust"

A short visit to the authors blog clearly shows they know what they talk about.


I am not going to make the claim that Rust devs are better, but when most people on this website make these sorts of claims, they are often referring to http://www.paulgraham.com/pypar.html

Note that a lot has changed since 2004 :)


> the kind of language Rust wanted to be

That has changed through the years: https://graydon2.dreamwidth.org/307291.html


Huh. You’re right.

I wonder why I thought it was written in rust.

How terrible of me not to check before saying that.


I see, thanks for commenting. I genuinely wanted to learn more about the background or context of that decision. Didn't know that it's a common thing to do in the Rust ecosystem! Nice to know, too.

"X written in Rust" is becoming a tiring clickbait pattern on tech boards.

Why not simply announcing "X" in the title?


> Look for example at what we can do (safely!) with Rayon in Rust

"Safely" for a certain kind of definition of safety: https://github.com/search?q=repo%3Arayon-rs%2Frayon+unsafe&t...


Production Rust code doesn't look like this.
