TWiR quote of the week

Actually the point is it finally compiles, you got there but don't get why as it's too late, but in the morning you find it is all correct :slight_smile:

...then go sleep and find your code correct and working in the morning

Woah, I know people say the Rust compiler is slow but I never had a Rust program that took all night to compile

i nominate the above exchange between @dunnock and @ZiCog.

...with the proviso that the first quote should be extended to make it clear that the second one is a tongue-in-cheek intentional misinterpretation of something that's originally talking about coding while not in full command of your faculties.

When I'm writing in Rust, it feels as though I'm actually able to think about the program, rather than wasting half of my effort going through the necessary rituals to stop the language from having a panic attack.

James Munns:

Hey @rustlang folks, is there a comprehensive writeup/reference anywhere of how the formatting machinery (format!(), write!(), etc.) work? Specifically from an implementation perspective (wrt trait objects, recursion)?

nrc:

It’s dark and ancient magic. I don’t think anyone knows it very well, never mind documentation

I kinda wish I could forbid arithmetic operators in my crates.

So, I'd say writing Rust without GAT is just like eating scrambled eggs without egg yolk, something is left to be satisfied.

Not about Rust directly, but the nice thing around it:

...in Rust there's a contract that if your function is marked as safe, it's must be impossible to misuse it for unsafe things even if you give your API to an infinite number of monkeys with keyboards.

I don't know if this is necessarily a good candidate for quote of the week but the discourse is pretty funny. Here is the thread on HN.

right?

Coding in C is like camping. It's fun for a while, but eventually you really miss things like flushing toilets and grocery stores. I like using C, but I get frustrated every time I hit a wall trying to build features from other languages. C is a very WET language.

Sorry it took a while to respond. I though the parent comment and that comment were funny. Since this feature was just released it seemed appropriate.

relatively speaking , my rust programs are like Leonardo DiCaprio in the Revenant, killing grizzly bears with their bare hands, dying and being frozen into a giant ice cubes then, surprise!, they're actually alive.

they can handle a lot, they tend to experience far fewer bugs that come around days or weeks after going into production.

my python programs, otoh, are like William Henry Harrison. Inauguration day! exciting! kind of chilly out here. uh oh -- pneumonia ... dang it!
