Rust is actually hard if you try to use it in something not trivial. Yesterday I was saying that the borrow checker is quite easy, but damn, it is actually hard. I’m using a bunch of .clone() to survive this - ThreadSky

This usually stems from not understanding ownership. Try reading through the ownership chapter in the book or in 100 Exercises to learn rust!

I’ve read the book from start to finish. I’m starting to get that the borrows while effective in making you aware of your code, they become a bit of a pain when you for example want to concatenate &str’s in a loop.

i’m not sure if i’m understanding this correctly, but it seems like in other languages i get the clone behaviour for free in most cases and never have to think about it.

in Rust, whenever I’m writing a .clone() I feel pain all over me 😅, but it feels necessary.

It’s a very steep learning curve at first. Nothing wrong with cloning to get it to work. Just go back later and refactor it down to remove them!

i’ll do that, thanks

i’ll look up the 100 exercises

If it’s easier, just push to a vec in the loop and then join after it completes

this might actually work

You’ll get there. The biggest thing you eventually understand is how the design of data structures and code impacts how difficult they are to make and maintain in Rust.

Learning this is an iterative process and one I find worthwhile. I’ve become a better architect and coder because of it.

thank you for the encouragement.
I’ll be patient
