the Rust book
Do you mean this? https://doc.rust-lang.org/book/
I actually started with that, but somehow redirected to "Rust by Example" and realise they were different, probably because of the same domain name and theme.
Now I see, they did start with explaining ownership, which is one of the things I felt that i was missing, when I started moving forward in "Rust by Example". Thanks for putting me back on track.
Oh I get it now.
Also, for some reason setting
vias$EDITOR, it is not able to load the contents of the file, unlikevimthat does.
