I mean, Rust has the additional thing that a reference is a pointer + a borrow, so it's not quite as similar to a pass-by-value.
And as for the dereference operator, occasionally you can use it to turn a reference into an owned value, often by making a copy of the value (but in that case, you can usually also use .to_owned()
).
A case where I don't think there's an alternative to the dereference operator, is if you've got a mutable reference and you want to replace the value that's underneath: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=04621490e1d0fd6fe1af7f2e843547fb
At the very least, if you remove the asterisk, the compiler will tell you very precisely that you need to add it back.
Here in Germany, I can pretty much only buy them shrink-wrapped, at least in the winter. They get imported from Spain, and I guess, the shrink wrap helps keep them fresh and undamaged during transport.
I imagine, this wouldn't be too different in the UK, but would be glad to be corrected.
