16a79cd567 Remove serde:🇩🇪:Error implementation for error::Error 
Serde forces us to be generic over which error our visitor returns, so we cannot return our error type.
So the implementation of serde's error trait is useless to us at this state.

Changed `expecting a type` to `into a type` to be more clear that the function actually returns a result of the respecting type.
