Imagine the following static metric generation:
```rust
make_static_metric! {
label_enum Methods {
post,
get,
}
struct MyStaticCounterVec: Counter {
"method" => Methods,
}
}
```
This will roughly expand to:
```rust
enum Methods {
post,
get,
}
use self::prometheus_static_scope_0::MyStaticCounterVec;
mod prometheus_static_scope_0 {
pub struct MyStaticCounterVec {
pub post: MyStaticCounterVec2,
pub get: MyStaticCounterVec2,
}
}
```
Rustc would complain that the `private type 'Methods' [is] in [the]
public interface (error E0446)` `MyStaticCounterVec`.
There is no reason for `MyStaticCounterVec` to be defined with
visibility `pub`. This commit instead defines `MyStaticCounterVec` with
`pub(super)` and thus `MyStaticCounterVec` does not expose the private
type `Methods`.

Maybe supplying some tests that will pass compile in this PR but will fail in master would be better! |
