I have a simple schema object SerialNumber

SerialNumber:
      type: object
      description: |
            A serial number of an entity. This is a basic string but with length limitations. Hence a separate type to uniquely
            identify such entities.
      properties:
       serial:
        type: string
        minLength: 5
        maxLength: 128
      required: [serial]

I used the openapi-generator to translate this to goalng with go-gin and the generated object is:

type SerialNumber struct {

        Serial string `json:"serial"`
}

Wondering what happened to the maxLength and minLenght specification? How do I know on the generated golang side what the maxLength/minLength are for a SerialNumber? I was expecting that the json tags would have the maxLength/minLength attributes.

What am I doing wrong?
