Given a file like:
```rust
enum Test {
Variant,
Variant2 {a: u32},
}
fn main(){
let x = Test::Variant("Hello");
let y = Test::Variant2("World");
}
```
The errors now look this way:
```bash
error[E0423]: `Test::Variant2` is the name of a struct or struct variant, but this expression uses it like a function name
--> file3.rs:10:13
|
10 | let y = Test::Variant2("Hello");
| ^^^^^^^^^^^^^^ struct called like a function
|
= help: did you mean to write: `Test::Variant2 { /* fields */ }`?
error: `Test::Variant` is being called, but it is not a function
--> file3.rs:9:13
|
9 | let x = Test::Variant("World");
| ^^^^^^^^^^^^^^^^^^^^^^
|
= help: did you mean to write: `Test::Variant`?
note: defined here
--> file3.rs:2:5
|
2 | Variant,
| ^^^^^^^
error: aborting due to previous error
```
