With some sprinkle of libraries such as anyhow and thiserror the Rust errors become actually pleasant to use. The vanilla way is indeed painful when you start handling more than one type of error at a time.

Go is like that abusive partner that gives you flowers and the next day makes you feel like shit. Then another day you go to an expensive restaurant and you tell yourself that maybe it’s not so bad and they still care. And the cycle continues.

Rust is an autistic partner that sometimes struggles with telling you how much they care, is often overly pedantic about technical correctness and easily gets sidetracked by details, but with some genuine effort from both sides it’s very much a workable relationship.

I have nothing against veganism as a dietary decision, I’m actually seriously considering it for health reasons and for easier food preparation.

I am sick of veganism as a moral high horse, especially with hypocrisy in the background. I have a friend constantly ordering stuff, including vegan ingredients, from Amazon of all places. If he’s going to low-key admonish me for hurting animals, I’d expect him to care about the Amazon warehouse employees to a similar degree. Unless it’s all just posturing.

An int& reference is just as much of a variable as int* const would be (a const pointer to a non-const int). “Variable” might be a misnomer here, but it takes just as much memory as any other pointer.

never mind, I looked it up. It’s a “reference” instead of a pointer. Similar, but unlike a pointer it doesn’t create a distinct variable in memory of its own.

I’m almost sure it does create a distinct variable in memory. Internally it’s still a pointer, specifically a const pointer (not to be confused with a pointer to a const value; it’s the address that does not change). Think about it as a pointer that is only ever dereferenced and never used as a pointer. So yes, like the other commenter said, like an alias.

It… isn’t poop?

The very notion of “less of a UB” is against the concept of UB. If you have an UB in your program, all guarantees are out of the window.
