How long does a reference remain valid after the object it references is dropped?

How to implement decorator in Rust?

QUESTION

How long does a reference remain valid after the object it references is dropped?

Asked 2021-Apr-08 at 23:47

I'm reading Common Rust Lifetime Misconceptions to figure out how lifetime works, one of the example (posted below) really shocked me, I can't convince myself why byte_1 and byte_2 still live well after the std::mem::drop(bytes); is executed.

From my point of view, the references which byte_1 and byte_2 hold should be invalid after the iterator bytes is dropped because the remainder array is dropped as well, the compiler should treat the drop action as an error, but in fact it pass the compiler and runs without problem...

Hope someone can give a reasonable explanation for a programmer coming from C++/C#, thanks!

bytes does not own b"1123". It only has a reference to it. Because there is no ownership, dropping bytes doesn't drop b"1123". Dropping bytes's reference doesn't affect other references with the same lifetime.

Now you could invalidate byte_1 and byte_2 if you were somehow able to drop the referent b"1123". But that's impossible. b"1123" has a 'static lifetime, and 'static objects can't be dropped.

QUESTION

How to implement decorator in Rust?

Asked 2021-Feb-21 at 13:08

I am learning Rust and I am stuck with a toy example. I have already read documentation on lifetimes, this post and a bunch of questions on Stack Overflow. I've spent more than a week, but I'm still stuck, so I decided to ask for help from a community.

I have a generic trait BookSide which returns BookIterator (which extends usual Iterator). And I have two implementations for both BookSide and BookIterator: ArrayBookSide and CommissionBookSide.

First one is stateful. It has a Vec under the hood.
Second one is stateless: it wraps some other BookSide.

My goal is simply to compile the whole thing. I was solving problems and followed the suggestions of the compiler. This process resulted in the following code.
