Description
While E0412 already provides suggested imports, E0433 does not. It seems like a similar problem on the face of it. Can we add suggestions for undeclared type or module?
Particularly this helps IDEs working toward rust-lang/rls#742.
For example no suggestion is currently provided for the following.
pub fn main() {
let set = HashSet::new();
}error[E0433]: failed to resolve. Use of undeclared type or module `HashSet`
--> src/main.rs:5:15
|
5 | let set = HashSet::new();
| ^^^^^^^ Use of undeclared type or module `HashSet`
