Right but as a general rule you'll mostly only be using `s.into()` to get a `String` from an `&str`. Or `&s` to deref `String` to a `&str`. I'm not sure why this would require a crate to handle?

The other ways are more "advanced", for when you're dealing with (for example) potentially unsafe coercions or you don't want to rely on inference for some reason.

I agree with you that I'm not sure what your parent is talking about, I'm just here to give all the examples. Deref coercion takes 99% of my String -> &str conversions, and I reborrow for that rare 1%, personally.

Yeah sorry, I'm just really confused about what's being asked for.
