Generate base struct from GraphQL interface to embed in type-based structs

[adrianlungu]

Hello,

Not sure if this is possible or I just missed it, but it would be great to be able to generate structs from the GraphQL schema that embed a struct that is based on the interface that subsequent types are implementing, i.e.

interface Vehicle {
 name: String
}

type Car implements Vehicle {
 name: String
 make: String
}

type Boat implements Vehicle {
 name: String
 hasSonar: Boolean
}

It would be great if the generated go code could be something like:

type Vehicle interface {
 GetName() string
}

type BaseVehicle struct {
 Name string
}

type Car struct {
 BaseVehicle
 Make string
}

type Boat struct {
 BaseVehicle
 HasSonar bool
}

Currently, it seems to generate structs based on the types only and repeating the fields from the interface in all of the structs; with a large number of fields, it gets very cumbersome to pass the interface data between the different types.

What do you think ?

EDIT: Found #626 which seems to address exactly this but there doesn't seem to have been any progress on this 🤔
