& to me implies address and * means get the value at the address, would that be a valid way of thinking that data's address contains the NewUser struct? This would mean web::Form is really the address of some struct T.
Or does Deref mean something else in this context.
The additional & is necessary, because as rustc tells us, it would mean moving the NewUser out, but that's impossible because data still owns it, so borrowing (&) the dereferenced NewUser allows us to send it to values without violating ownership rules.
An alternative would be to do values(data.into_inner()) which moves the NewUser out of the web::Form by consuming it.
By the way, Nivethan, this is a wonderful series. Thank you so much for the effort you put in!

Ah! Thank you that makes sense.
