Description

I think this video (https://youtu.be/iVYWDIW71jk) by @jonhoo is really helpful to understand "Subtyping and Variance", I'm wondering if we could steal some information from it. But the current chapter is long and an additional explanation may be overwork here, so a link to the video might be fine.
@jonhoo If you have any thoughts on this, I'd love to hear it :)

Research direction

Read the existing Subtyping and Variance chapter at doc.rust-lang.org/nightly/nomicon/subtyping.html and watch the linked Crust of Rust video. Decide whether the chapter needs added explanation or only a video link; done means the chosen improvement is incorporated into the chapter and its documentation remains clear.
