TWiR quote of the week

I don't think we should be linking to the Phoronix comments section, no matter what someone says there.

From Why choose rust over C or C++:

@zireael9797

... I once convinced a friend to check out rust by telling him "it shows snippets of the code in the error outputs, underlines the problematic bits in pretty colors and even suggests fixes to your variable name typos"

Humor by @FedericoStra in response to

@alice do you have a flat_map method?

What is a monad? And who needs Haskell anyway?

I lived for two years in a tent, wandering around the desert. Whenever I needed to clean the interior, I used a flap_mat method. I guess that made me a nomad.

unsafe Rust is all about flirting with UB but never giving in.

Once you realize that the Rust borrow checker is actually preventing you from writing bug after bug, you start to wonder how we ever got this far without it.

Empowering is the perfect word to describe Rust in 2020. What used to be a rough adventure with many pitfalls has turned into something beautiful, something that can lift your spirit. At least, that’s what it did for me.

That "If it compiles it works" is legitimately no joke. I mean, it's obviously not universally true, but I have worked with projects of this scope in other languages, and I have never had anything work even close to this well in the first run before.

If you've never tried Rust, imagine pair programming alongside a nearly-omniscient but narrowly-focused perfectionist.

Perpetual n00b struggling with ownership (again)

You're not allowed to use references in structs until you think Rust is easy. They're the evil-hardmode of Rust that will ruin your day. Use Box or Arc to store things in structs "by reference". Temporary borrows don't do what you think they do.

@http://blog.vmsplice.net/2020/08/why-qemu-should-move-from-c-to-rust.html

Rust has a reputation for being a scary language due to the borrow checker. Most programmers have not thought about object lifetimes and ownership as systematically and explicitly as required by Rust. This raises the bar to learning the language, but I look at it this way: learning Rust is humanly possible, writing bug-free C code is not.

I'll admit, I've sat at my desk with a huge smile thinking "I couldn't have built this without lifetimes."

The amount of careful thought I've seen put into [Rust's] design – crafting async/await to work in no_std environments, or the new inline assembly syntax – has produced a language that is not only better than what I could have designed, it's better among axes I was not even aware existed prior to reading the Rust RFCs.

This is not a commentary on the actual issue that triggered this response. Rather, I just liked the response.

@Yandros

If you don't want to use the tool that gives you compile-time properties, you will need to pay runtime cost

[josh]

Whoop whoop, this feels like being knighted, and all the work totally paid off. Iteration after iteration after iteration, and it really was just Rust pushing me into doing "what's right", which also happens to be fast as a freebie.

[ssokolow]

There is a more technical term for "wrong", too - maintaining invariants is maintaining "soundness". Code that breaks invariants is called "unsound".

-- Frustrated? It's not you, it's Rust

[alice]

You're smarter than Rust - and you may need to rethink your design a bit, so it's possible to tell the compiler about it.

And when you do, you'll discover mistakes you never knew you could make.

“macros are for when you run out of language”. If you still have language left—and Rust gives you a lot of language—use the language first.

Not only is our new Rust code simpler and cross-platform, but it’s faster to boot!

Programming's always been frustrating. Rust just makes the frustrations more likely to happen to you, and not your users.

Sometimes all you really need is an enum.
