use std::collections::HashMap;
^---- if I add a '{' here it would be great if
you added a closing '}' before the semicolon.
I can't personally think of a situation where I wouldn't want that.
Quite often we go from one import to two, and at that point we have to introduce the braces. You could even add a ', ' and put the carrot before the closing brace, but I think that might be a little disconcerting.
Also the corollary,
use std::collections::{HashMap};
^ if this '{' is deleted then it would be great to auto remove the closing brace.
