Description
It would be very useful if the "show type size on hover" functionality was available for anonymous futures, i.e. the types of async blocks and return types of async fns (when hovering the function name, I guess).

Research direction
Start by reading the existing “show type size on hover” handling and trace how hover requests identify named types. Extend that path to anonymous futures from async blocks and async fn return types when hovering the function name; done means the future size is shown consistently for those cases.
