Is Rust supposed to be that hard? (lemmy.today)

I decided to adventure myself in Tauri development for a personal project, I read the entire Rust official book and followed the exercises. When I first started developing it was like if nothing I learned helped for real life projects.

Now after getting betting up every single time I touch my project, it seems I'm catching things slowly.

But I've never seen such a hard modern language, I used C and C++ before and it's incomparable.

Do you really need that much Rc? That is, do you really need multiple ownership for a piece of data in a single thread? It is rarely the case, many times you can get away by just borrowing that data.

ARc is harder to avoid, since across threads you often really need the multiple ownership.

Next is, do you need RefCell? Or would a simple Cell in some of the struct fields be enough?

    I recently picked up embedded in Rust and I often stumble upon the pattern of taking buffer references into structures, and I would want to pack the buffer and the struct that uses it together, but I don't want to do self referential magic, so for now I keep buffers passed around everywhere

    Yeah. That's a huge issue rust has. However, it can't be solved with Rc.

    You either do it in safe rust, by "cheating" the borrow checker and storing a size offset of the buffer instead of a reference. Or just use unsafe rust and store a raw pointer alongside the buffer.
