Missing documentation for N::n

[Laura7089]

There is no documentation available in the generated n function.
Coupled with the default pub visibility of the function, my #!warn(missing_docs)] lint is going crazy!

Looking at the expanded macro, it looks like it's not passing through the #[allow(missing_docs)] that's on the actual type to the generated impl block, even though other derive std macros are doing so.

I'm running into the same issue, is there any work to fix it?
