OpenAPI/Swagger struct generation

[denismakogon]

Nice to see that I'm not the only one who wants to generate code from JSON.
However, plain JSON/YAML is the only notation that can be used as a source for code generation.

I'd like to propose OpenAPI V3 generation, assume you have the following JSON file:

{
  "type": "object",
  "properties": {
    "error": {
      "type": "object",
      "properties": {
        "message": {
          "type": "string"
        },
        "fields": {
          "type": "string"
        }
      }
    }
  }
}

this JSON file may end up in a go struct like:

type Error struct {
    Message string `json:"message"`
    Fields string `json:"fields"`
}

type SomeStruct struct {
    Error Error `json:"error"`
}

thoughts?
