Add "Expected output:" comment
First thing first Amazing project has been fun so far.
Now I'm currently in the move_semantics2 and I'm unclear what the output should be. I Solved it, to the point where it is compiling, as well as read the hints and tried all 3 solutions.
But I'm expecting the output to be Vec0: [22,44,66] and for Vec1: [22,44,66,88] but im always getting:
Vec0 [] Vec1[22,44,66,88] is this what it should be ?
It seems like having "is able to compile" as the only win condition is a bit confusing (this obviously doesn't apply to the parts with Tests but I don't think its necessary to apply test rules to every part a simple Expected Output: .... section would suffice." IMO.
any thoughts ?
The goal of this exercise is ambiguous, I agree. I ended up looking up what others have done to get the code to compile, and all I find are ones where the vec0 is empty... Meanwhile, the hint implies that you should fix dropped variables, which people don't appear to be doing? It does pass the "Make me compile without changing line 13 or moving line 10!", though.
I am also confused about this exercise and the hints. The first hint says to "Make another, separate version of the data that's in vec0 and pass that to fill_vec instead.". But vec0 is empty so there is no data to copy?
The last hint is "Make fill_vec mutably borrow a reference to its argument (which will need to be mutable), modify it directly, then not return anything. Then you can get rid of vec1 entirely -- note that this will change what gets printed by the first println!". But then the code in maindoesn't make sense.
This really stumped me because of those expected comment lines. I have no idea if the 3 ways I did it match the 3 hints given. It almost seems like that expected output should be for move_semantics3.rs
