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
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 thought it was randomly adding Send and Sync traits to function signatures until rustc is happy.
That too
Randomly wrapping things in Arc::new()
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<>>>New your program deadlocks instead of crashing, peak safety.
EVERYBODY STOP. Nobody make a move or the memory dies. We have a Mexican Memory Standoff.
So… now the
rustcborrow checker is the new video game boss that is nearly impossible to beat for newcomers, right?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.
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.
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
Same for C, & yields a pointer to a value, and * allows you to access the data. (For rust people, a pointer is like a reference with looser type checking)
We have pointers in Rust, too :) see documentation
I doubt many people have ever use that or any of the other low level memory API. The main appeal of rust is not having to do that.
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.
