When a trait is used without specifying the implementation (e.g. calling
a non-member associated function without fully-qualified syntax) and
there are multiple implementations available, use a placeholder comment
for the implementation type in the suggestion instead of picking a
random implementation.
Example:
```
fn main() {
let _ = Default::default();
}
```
Previous output:
```
error[E0790]: cannot call associated function on trait without specifying the corresponding `impl` type
--> test.rs:2:13
|
2 | let _ = Default::default();
| ^^^^^^^^^^^^^^^^ cannot call associated function of trait
|
help: use a fully-qualified path to a specific available implementation (273 found)
|
2 | let _ = <FileTimes as Default>::default();
| +++++++++++++ +
```
New output:
```
error[E0790]: cannot call associated function on trait without specifying the corresponding `impl` type
--> test.rs:2:13
|
2 | let _ = Default::default();
| ^^^^^^^^^^^^^^^^ cannot call associated function of trait

2 | let _ = </* self type */ as Default>::default();
