Rustlings questions removed?

Recently there was a topic about a rustlings exercise, as_ref_mu.rs, in this group. I made a reply with some code and in my code was some "errors" in my comments and in my thinking.

Do the topics with rustlings answers get deleted? I don't see any message telling me my post was deleted. I also can not seem to find the topic or any other "rustlings" topics when I search.

Rustlings: how to generalize AsMut for Box<T>?

I'm working my way through Rustlings 5.2.1 in conversions/as_mut_ref.rs, so Spoiler Alert! The current version of this exercise asks us to add a trait bound and implement a function that takes a mutable reference to a number and squares the number in-place. Here's the test that runs the function num_sq(): #[test] fn mult_box() { let mut num: Box<u32> = Box::new(3); num_sq(&mut num); assert_eq!(*num, 9); } A simple solution for num_sq() would be this, but i…

Well that is embarrassing.

I was searching by "Relevance" and the word "rustlings" I even included the file name "as_ref_mut" but see now that the OP has the file name as "as_mu_ref" in text.

Thank you both for the help, and everyone else that had to read this thread for putting up with the noise.

When I search for things on this forum, it's usually relatively recent things (and certainly not 5 year old things), so I almost always end up hitting the "expanded search" button and changing "relevance" to "latest post".
