[Feature request] Define spec for structs

[fermuch]

As described in the docs there is already a mapping of field to type.

And the decode/1 function is using a generic struct.
As an example of the generated code:

@spec decode(binary) :: {:ok, struct} | {:error, any}

Would it be possible to generate a @type t for the structs?

Hi 👋 Thank you for your suggestion! It's a very good idea 🤔 I'll try to take a look, but I can't make any promise 😉
