Oh and .clone()
And .copy()
.copy()?
Are you copying a
ResultorOption?I don’t understand…? I think I never explicitly run a method/function that is called copy (there isn’t at least not for the trait
Copy)Lol yea I think the .copy() comment was a little gaslighting or something.
no its not youre crazy
I thought it was randomly adding Send and Sync traits to function signatures until rustc is happy.
That too
Randomly wrapping things in Arc::new()
This was me in courses that used C. Keep adding and removing * and & until the IDE was happy and it usually worked.
Ah the good old times with C, when things were much more simple (but unsafe…)
(void*)flashbacks intensify.The “best” way to program dynamically typed…
I’m gonna have to borrow this book
Me too. I also want to make some changes to it at the same time.
Better apply for a mutable library card now before someone else does
Hahaha yes tfw Rust forces you to put your shit in a
Rc<Cell<Option<>>>deleted by creator
EVERYBODY STOP. Nobody make a move or the memory dies. We have a Mexican Memory Standoff.
Follow up of: “Mmm… should I put lifecycle annotation in these 10 structs or just use and Rc and call it a day?”. Rc and Box FTW.
So… now the
rustcborrow checker is the new video game boss that is nearly impossible to beat for newcomers, right?I think that’s the only thing I dislike about rust. Not having to use * to dereference but later having to use is tad confusing. I know it’s still clever solution but in this case I prefer c++'s straightforward consistency.
Using ampersand never was problematic for me.
C++ does have the problem that references are not objects, which introduces many subtle issues. For example, you cannot use a type like
std::vector<int&>, so that templated code will often have to invokestd::remove_reference<T>and so on. Rust opts for a more consistent data model, but then introduces auto-deref (and the Deref trait) to get about the same usability C++ has with references andoperator->. Note that C++ will implicitly chainoperator->calls until a plain pointer is reached, whereas Rust will stop dereferencing once a type with a matching method/field is found. Having deep knowledge of both languages, I’m not convinced that C++ features “straightforward consistency” here…

We have pointers in Rust, too :) see documentation

Sure, but raw pointers and unsafe Rust are still covered in the official learning material, so I assume that most Rust devs know about raw pointers.
Replace that with golang and now we’re talking
Yeah, popped in the comments to say the same.
I dont know what my damage is with pointers…
honestly with Go in general I’m in a perpetual cycle of being annoyed with it and then immediately being amazed when I find some little trick for efficiency - with stringer interfaces and the like
