Plug and "unfetched" connections

[easco]

In the Plug documentation for Plug.Conn (http://hexdocs.pm/plug/Plug.Conn.html) under the header of Fetchable Fields it says

Before fetching those fields return a Plug.Conn.Unfetched record.

I'm afraid that I don't understand what that means.  Does it mean that my handlers are not supposed to return a conn structure for which I have already fetched one of the fetch able fields?

It means that if you access conn.params before calling fetch_params/2 or invoking Plug.Parsers, it will return a Plug.Conn.Unfetched struct. The docs are wrong though, it returns a struct, no a record.

OK.  I'll see if I can submit a pull request which I hope will clarify the docs.  Thank you!
