Foo::bar() invokes do not give suggestions for Foo when it is not in scope #52468
Description
In this example:
fn main() {
let _: HashMap<u32, u32> = HashMap::new();
}there are two uses of HashMap. Neither is in scope, but only the type gives me a suggestion for how to import it:
error[E0433]: failed to resolve. Use of undeclared type or module `HashMap`
--> src/main.rs:2:32
|
2 | let _: HashMap<u32, u32> = HashMap::new();
| ^^^^^^^ Use of undeclared type or module `HashMap`
error[E0412]: cannot find type `HashMap` in this scope
--> src/main.rs:2:12
|
2 | let _: HashMap<u32, u32> = HashMap::new();
| ^^^^^^^ not found in this scope
help: possible candidates are found in other modules, you can import them into scope
|
1 | use std::collections::HashMap;
|
1 | use std::collections::hash_map::HashMap;

Maybe, once the current ticket is resolved, we should also elide suggestions to only appear once the first time they're needed.
