Hello,

my swagger.yaml contains following lines:

TypesResponse:
type: object
properties:
Types:
format: int32
enum:
- 0
- 1
- 2
- 3
type: integer

I used the generator v7.6.0 to generate a rust client. The client throws an error when parsing the response. The response is like

{"Types":2}

. It seems serde_json throws - it expects a response like

{"Types":"2"}

. So the client expects the 2 be in quotes. But the yaml states "type:integer".

For me it seems like a bug in the generator - or do I misuse the generator? Thank you.
