Description
Summary
The compiler should error out as MyStruct cannot be accessed.
Reproducer
I tried this code with flag -frust-name-resolution-2.0:
pub struct Str(i32);
mod test {
pub fn test() -> Str {
Str(0)
}
}
Does the code make use of any (1.49) nightly feature ?

Actual behavior

I expected to see an error suggesting use MyStruct.
